Hello! Bought your plugin a while back haven't had the chance to test it much, but I have a few questions if that's ok: - Is there any info about the performance of this on phones when exported to android? I played this demo on my phone through the browser and runs just fine, wondering how it would perform as an app.
- Does it support alpha on textures? And if so, does it have the same problem that Construct 3's 3D objects have in which it doesn't draw objects that are behind alpha textures properly?
- Can we expect any sort of texturing other than diffuse in the future? For instance normal maps or specular mapping?
Perf on Android seems reasonable based on feedback, however you can't push it too hard. As per usual, I suggest experimenting.
It supports alpha on textures, in general 3DObject uses the C3 rendering SDK, so it has those limitations, I have requested some features to help us get around that, but we'll see if Scirra implements it.
For other texture maps, it is a similar situation, I did a request to Scirra so that I might be able to implement normal map, etc. still waiting on a response.
It takes a very specific setup for the animations and export settings to get it to work. I eventually reverse engineered how the fire golem model actually works with animations. Unfortunately I can't really explain it here but it does work if you tinker with it. If it works in the Babylon sandbox as it should then it's set up properly and should work in C3 the same way.
Corlenbelspar is right, this is not an issue of the plug-in, it is probably due to how the model and animations were created and exported from the 3D modeling tool such as Blender. I would try googling for information about animations, exporting and your specific workflow / tools.
The only combo I can get to work without crashing is C3 at 327.2 (stable) and 3dobject at 2.35.3 - anything newer than that for either C3 or 3dobject causes a crash on confirming the 3d object file name or re-opening the file. Is this a known thing, or is the issue possibly on my side? Thanks.
Hmm, something strange is going on, I have heard similar from another user. If you see the error again, I would appreciate seeing the project, so I can debug. You can contact me on the Construct Community Discord: Mikal#1464 if you need to DM the project instead of posting a link here.
There was a C3 issue that caused problem with project files, the latest release was a workaround that solved _some_ of the problems (but obviously in your case caused more.) I made the last version before this change available again.
In the latest C3 beta version, a new SDK API was added to fix the C3 issue and I will release another version (which requires the use of the latest beta later tonight.)
Thanks for the detailed error report, it is appreciated to help me through the process of debug.
Please try the latest version 2-36-4, updated to use the new C3 SDK available in C3 beta r330. If you still see errors, please send a demo project, so I can do further debug.
You can contact me on the Construct Community Discord: Mikal#1464 if you need to DM the project instead of posting a link here. Please also try R331: https://editor.construct.net/r331/ (it helped other people.)
super plugin - but cannot rotate an object on any axis. I am creating objects on a grid and I want them facing a random direction. When I use set x,y,z rotation I set x = random(360) ,y=0, z=0 and which rotation order should I select? - have I got it wrong? I have been using this plugin for a while and this is the only problem I have found
Thanks! The rotate x,y,z should work, I use it in my projects, can you please show a sample project? The order doesn't actually matter anymore, because of an underlying change, but I had to keep that parameter in there to not break older projects.
On loaded is a trigger, you typically cannot include two triggers in event blocks.
So, in your case above, just create a separate top level event block with 'On loaded and set rotation', then as each is loaded, it will set a random rotation. Remove the 'Is loaded' from the loop.
Hello, I bought your 3D plugin yesterday, thinking it would be very useful for us. I like it very much, it's very useful, thank you. However, as you can see in the video, when the PLAYER moves straight, he stays in the middle of the screen, when he moves left and right, he does not follow the camera and leaves the screen. I tried hard but I couldn't. I would be glad if you help.
It looks like you are trying to implement a third person camera. To do that, you need to both rotate the camera angle and the camera location around the player. See this great tutorial on how to design a third person camera in construct.
I do not know of a way to enable that on itch right now and I do not have an alternate service. Can you buy addon on the C3 website, I could look at loading it up there also.
Hi! A quick question: does hiding nodes saves performance? I've been thinking of making a small customization system inside a character. Will it hurt if a model have a lot of sub-meshes inside of it? An absolte most of it would be hidden of course P.S.: Thanks for constant updates and responses!
Good question. Right now, hiding nodes helps with draw performance and I'm actively working on another change where it will also help with animation performance (it already works for worker animation and I'm also updating non-worker animation.) I and others are doing the same thing for customization of different instances of a single model. Also - you are welcome :)
Sounds very exciting! Absolutely looking forward for it! So if I understand correctly, current version should have worker animation enabled for proper testing?
Hey! Your plugin looks amazing I intend to buy it, but I need you to tell me the plugin is still under development receiving new updates? any chance of this plugin being abandoned, I say this because it makes me afraid if the plugin is ever left behind with bugs
I know what you mean, but unfortunately the C3 effects system for 3DObject and 3DShape only works on the final rendered full 3D image. It does not allow for per face effects.
That being said, there is a possibility to make a new effect which uses large changes in depth to delineate edges that could operate on the entire image, I will think about that...
ok ty, its kind of hard to tell where a corner is of a wall without shadows or lines or anything, ill try to fake it with textures for now til theres a solution.
I am currently having some trouble making a 3d object texture work when imported to C3. The original object needs its texture mapping to be set to "extend" instead of "repeat", but when i apply those changes in blender, and import the model to C3, the texture still shows up as repeat. The problem is that it works fine on babylon and other sites, and it only shows up wrong in C3.
One basic way is to have a 3DObject with a walk animation, add a 2D sprite with 8 direction behavior, use an event to match 3DObject rotation and location to the 2D Sprite, make the 2D sprite invisible and then use the 3DCamera object to set the camera how you want.
I don't have an example with events. It would be events like set rotation, set 3DCamera parallel to canvas (for that view) and set position to track the 2D Sprite.
Realy nice addon! I use it many times. What you think about physics system as a behavior or an addon? And we still need a lighting/material system)) Оne day, you can do it, I hope.
Yes, outside this plug-in. I have seen people use raycasting to do this, or collision filter based on z-elevation. I think there are some examples in the Construct Community Discord, so you could also look there.
You could use a physics engine like cannon-es, but you will need to know JS to use it. There is an example of general cannon-es usage in the devlogs.
How well is instancing in Blender handled in this? I saw it does work, but I can't tell if there's a performance boost or not like would normally be the case.
In general it just treats the instances as an additional mesh to render, so performance would be similar with the same number of polygons between an instanced model and non-instanced model.
Prefab will share texture memory between instances, so that will help GPU memory. In general, what is your concern? CPU memory? GPU memory? Performance?
I see - it won't change that. If we need to draw a poly, there are not many ways to improve that, except by batching. In this case batching for a particular model is most dependent on texture changes, so if you use a texture atlas / single texture for a model, it will be able to batch well.
After installing the add-ons I've tried to open the c3P files, but the same message keeps popping out. "Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project" Any idea what may be happening?
I am not sure why, I tried it in an incognito window and installed the latest addon and the Meshpoint example file and it worked fine. When you see this error, can you open the javascript console and see what errors are reported, a screencap will help me see what is happening. Which version of C3 are you using?
I am glad you got it working. One possible reason is that the addon loads the gltf/glb files during runtime, so the c3 runtime must be able to access them during runtime.
This is an awesome thing to have exist, thanks so much for this.
However a limitation I've run into while experimenting with it to double check what it can achieve, is no matter what I can't seem to get 'backface culling' to work for it (so you can see through the back of something, e.g. to achieve targeted toon outline with black texture+backface culled). I've tested different material settings (using blender), editing the file itself with a text editor (""doubleSided" : true," exists which I thought my be the term required, but true or false changes nothing), all the blend modes, searched through here/the forum thread in-case, etc.
Would appreciate knowing if this is a hard limitation, something I missed, or something that just needs to be parsed from the file in a possible update. Note that this worked without issues in the babylon.js sandbox.
One of my goals for this addon is to use the exposed C3 SDK, to keep compatibility with C3 as time goes on. The impact of that is some limitations, due to C3 limitations around how C3 limits changes to the webgl render, fragment and vertex shaders. So, in those regards, material settings in blender are generally not supported. Only simple base color texture is allowed in the render. In addition, C3 does not enable webgl render back face culling (through debug, I have found that it is disabled, just as an experiment I have tried forcing enabling it globally, but other C3 non-3DObject objects are not rendered correctly.) There are also other C3 issues around transparency and ordering.
I imagine it works well in the sandbox, since babylon supports full Metallic-Roughness PBR model.
If you want to share a project, so we can experiment, let me know.
The only _slow_ way I know of doing this, would be doing back face culling on the CPU during render in the addon, which would chew up a lot of CPU perf.
Yeah I imagined it wouldn't be able to do much relative to blender materials, but I also imagined backface culling was about as regular as it gets to the point of expecting that be the default, so was surprised when I couldn't get it.
Yeah that CPU culling doesn't sound like a possible solution to be trading that much performance away. When you say force enabling of back face culling causes issues with non-3DObject objects, does that mean if your project just uses 3DObject's then, this could be an option? Or does your followup comment mean there'd also be further issues introduced if trying to take advantage of 3d located particle sprites too like in your 3DMeshPoint example?
I've got a blender, gltf, and minimal project (the model in it) here. Also a minor and not so minor thing, in the editor the 3d model textures are softened-but it does respect the nearest/point setting when you play the scene so it's not a big problem if that can't be resolved. However also, maybe a limitation of C3, possibly a rendering option though, but the softening of the texture also softens the alpha, and this causes that to pierce through other object as seen here (the left side has separated objects where as the right sides are merged so you can see it pierces per object).
Would be awesome if you could make some advancements with this as backface culling is an especially valuable technique when having to work with a more restrictively performant 3D environment, but I can understand if it might not be possible. Appreciate you're still willing to try and tackle it/have already made attempts.
Here's a hack method - note how it effects the rotating C3 sprite though! I also have not tried with varying the camera, but I imagine it should be ok.
Thanks so much for that :) . Looking at it it seems everything by default for some reason is backfacing (you can see the text rendered, even if on a '2D' layer, disappears with back culling).
It'll be a bit awkward, and limiting/additional steps+triangles required (duplicated and normals flipped) to fix areas of a model you actually need to see both sides of. However for the scope of the game I'm wanting to make, this solution will allow me the end result I'm looking for so thank you very much for that. The trick required to finish the effect is having to flip all 3DObject normals before exporting, that way you can hide the 'front facing' faces (that are now back facing), and hide front-facing instead. This way regular construct objects (at least besides construct 3d shapes) will stay visible.
It looks more like the typical difficulty with 3D transparency, sorting, depth buffer and render order. It is not yet easy to solve in C3 (or 3D engines in general!)
Have you considered point light sources (no LightLayer3D) and working with shadows.
I remember the Q3D (banned by Scirra) on the C2. Point light sources worked very correctly there. You had to place them as a 3D model, adjusting the height... but they worked...
Point light sources need more information exposed in the C3 effect SDK, I have requested this, but no response yet.
In general 3DObject is not a full scene 3D addon, it is focused only on the model itself/object itself. I would classify Q3D/three.js/babylon.js as more scene based engines.
This definitely looks like a transparency / depth buffer / render order issue. Is the light cone a 3DObject or a 3DShape? Have you tried placing the light cone on a different layer (probably a higher layer)?
Hi. I have solved this problem. You need to add Z-elevation. When 2 models are on 1 line, one model overlaps the other. Not mash on one Z-elevation. Center point model in one z-elevations. Model with additive display - removes part of the other model.
p.s.
>> 3DObject or a 3DShape? - any maybe, i/.m use both
But i have new. 2D transparent sprite placed in 3D layer ))) any z-elevation... sprite with any blendmode if z-elevation with "-"
>>Cool looking art! What kind of game is it? Thank you. my wip.
The plug-in only works with diffuse textures (albedo), not bump map, normal map or other texture shaders, I wonder if the model you are using is more complex in terms of textures and shading. Only the diffuse texture will be rendered. Can you share the glb model?
thinking about getting construct 3 with this. can this run about 100 low poly animated models on screen without lagging? ive tested with the 3d cubes only and that was fine.
it can run 100 low poly models, how ever you'll experience lag while working on the game. but when the game is exported most of the lag will clear up. I also recommend adding an optimizer script like this help reduce lag.
both are important but animation rate costs the most cpu usage. I believe that even if you change the visibility, the animation is still calculated to its fullest so its still best to reduce that to keep smooth gameplay.
thanks for your hard work。the uv ctrl is real nice,and i hope we can ctrl mesh point，so we can make a man hit 3dobj obj transform at hit point，and ctrl more element like bone，it，must difficult to do it
I'm interested in creating 3D games in Construct3 with Minecraft-style graphics, but I'm new to 3D. How do I create the 3D models? i.e. what free tools/formats are best?
I love it - but one problem cant apply car behavior? I can accelerate but cant steer? I can also rotate xyz but doesnt update car.movingangle if i do that
Thanks to Dev - creating a sprite and pinning the 3dObject to it did the trick (also put the rotation update in everytick seemed to be more reliable than pin behavior)
You probably should just use an invisible sprite object with car behavior and add the 3D model as a child to it then change its rotations to the angle of the sprite however is appropriate for your game. C3 only has one rotation in 2D that it understands and models have three different rotation values that are unrelated.
works like a charm, so happy I found this <3 one thing though, it seems I cannot rotate an object with actions, I can set angle in properties, but cannot do so with actions.
Even if you add it to a hierarchy so to force its angle, it does not follow, here is a gif I recorded
can this be worked around? I was eager to use this in a project =)
Can you describe in more detail what you are trying to do with the 3DObject in regards to an angle? I don’t think I understand yet, because I thought rotation would do what you want.
Has anyone figured out an efficient workflow for taking the Synty POLYGON characters, importing non linear animations for them and then exporting them as gltf? I've been trying all night, trying mostly with blender but also trying gltf export plugins in unreal engine that didn't work. I just wanna build up my library of animated characters in .gltf >< not a lot of gltf model packs online except for quaternius
Is there some way to pin an object to a position on a model? So when the model rotates or moves via animation etc, the object will stay at that same relative position.
No not yet, in fact the gltf format does not have a center point per mesh. I may look at this in the future and if so I’ll probably do average, which will cost some performance.
That's fair. I figured you would have to do something C3 side that would be at the expense of performance to some extent because I've made stuff in Blender and didn't see a way gltf could store it.
It would probably still definitely be a useful feature if used appropriately. Like attaching objects with collision boxes to damage the player if a limb hits them or chain models together maybe.
Currently I'm using the plugin for giant bosses in my first person horror game and some other various things that only it can pull off. Otherwise enemies and stuff are like DOOM billboards. So pinned objects might work fine in that setting.
This is a great plugin though. I've been using this stuff since Construct 2 and I never thought we'd be having full 3D some day even if only cosmetic.

Kindeyegames, do you think it would be possible to port this plugin to Gdevelop? (Plugins in Gdevelop are called extensions).
Both engines are EXTREMELY similar in every way, the only difference is that Gdevelop is free 🤔
Not at this time, I do not use Gdevelop and I use C3 for my work, so I need to focus on that.
Some ideas:
Flipped normals for outline effect. Is it possible?
Animation blend control as a event.
Don't have access to normals during the initial quad rendering due to C3 limitations. However, try the usual 2D outline effect.
In terms of animation blend control as event - do you mean set the blending time?
yep! blending time!
Ok, will add that to my feature list, will get to it.

Hi. I do not know why, but my animation does not change. Only the one that was included in Blender is constantly working.
Did you try your file on https://sandbox.babylonjs.com/ does it have more animations there?
No, only one animation is there
It takes a very specific setup for the animations and export settings to get it to work. I eventually reverse engineered how the fire golem model actually works with animations. Unfortunately I can't really explain it here but it does work if you tinker with it. If it works in the Babylon sandbox as it should then it's set up properly and should work in C3 the same way.

2-36-4 requires C3 beta r330 as noted in the devlog notes, have you tried that?
Yes - it did crash C3 as well.
However, r331 was released just now - and it works with 2.36.4 for me - no more crashes/issues. All is good.
Hmm, something strange is going on, I have heard similar from another user. If you see the error again, I would appreciate seeing the project, so I can debug. You can contact me on the Construct Community Discord: Mikal#1464 if you need to DM the project instead of posting a link here.
its crashing if u create new 3dobject and type the wrong path name, but it doesn't if u type it correctly the 1st time.
Please try 2-36-5 for a fix for this.

I want to set just the x to a random angle but it seems to ignore all axis
thanks
Ah, I see. Try waiting for the model to be loaded before setting for now, I'll review and see if it can be changed to also work before it is loaded.
Thank you, that sounds like the fix but it still won't work for me. have I got an old version? mine has "Is loaded" you have "On loaded"
On loaded is a trigger, you typically cannot include two triggers in event blocks.
So, in your case above, just create a separate top level event block with 'On loaded and set rotation', then as each is loaded, it will set a random rotation. Remove the 'Is loaded' from the loop.

Hey, i am in a country where i can't really use paypal, can i buy it using some other method?
I can't use paypal either. Purchase with my debit card.
I do not know of a way to enable that on itch right now and I do not have an alternate service. Can you buy addon on the C3 website, I could look at loading it up there also.
Thank you for your answer, I can't find the C3 version, could you link it here?
It is not there yet, I wanted to check if it was there, if you could buy it, before I did the work trying to get the addon approved there.
This should be a built-in plugin in construct 3 :)
Agree!

Actively working on it. No real comment on any chance of it being abandoned, I don't know how to answer that.
Acquire your plugin, now I will learn how to use it, congratulations for your creativity, God bless.
Good afternoon!
I really liked your "Contour Glow and Glow Worm Effects for Construct 3".
But I can't pay by bank card, is there any way I can pay you with cryptocurrency ?
I'll check if there Is a way to enable crypto payments on itch.
If there is such a possibility, it would be wonderful.
Because, unfortunately, bank cards of my country do not work on this site
I don't see a way to do this, can you contact me on the Construct Community Discord? Mikal#1464
How to add 3d Outline to an object? Outline effect works but doesn't apply in the inside edges .
I know what you mean, but unfortunately the C3 effects system for 3DObject and 3DShape only works on the final rendered full 3D image. It does not allow for per face effects.
That being said, there is a possibility to make a new effect which uses large changes in depth to delineate edges that could operate on the entire image, I will think about that...
ok ty, its kind of hard to tell where a corner is of a wall without shadows or lines or anything, ill try to fake it with textures for now til theres a solution.
Try using the layerlight3d effect, it can help with this case.
Just draw them on the texture
Hi,
I am currently having some trouble making a 3d object texture work when imported to C3. The original object needs its texture mapping to be set to "extend" instead of "repeat", but when i apply those changes in blender, and import the model to C3, the texture still shows up as repeat. The problem is that it works fine on babylon and other sites, and it only shows up wrong in C3.
This was fixed on the new update! Now the texture wrapping works perfectly.
how do you make 3d objects walk?
One basic way is to have a 3DObject with a walk animation, add a 2D sprite with 8 direction behavior, use an event to match 3DObject rotation and location to the 2D Sprite, make the 2D sprite invisible and then use the 3DCamera object to set the camera how you want.
what would the event be
I don't have an example with events. It would be events like set rotation, set 3DCamera parallel to canvas (for that view) and set position to track the 2D Sprite.
you should make a example
I posted a simple example to get you started. It was saved with the latest beta of C3.
Realy nice addon! I use it many times. What you think about physics system as a behavior or an addon? And we still need a lighting/material system)) Оne day, you can do it, I hope.
translated via google translate
Perhaps one day, but for now if you understand JS you can look at the rocket example which uses cannon-es physics.
do you have any example with Dark and light ?
I need this for my new game in dark caves, player should hold torch ?
Try the layerlight3D effect, this works somewhat like the player having a torch.
Hello. Best Regartds. Is there any way to make collisions, or make it possible to walk on inclined planes? (3d platformer for example)
Yes, outside this plug-in. I have seen people use raycasting to do this, or collision filter based on z-elevation. I think there are some examples in the Construct Community Discord, so you could also look there.
You could use a physics engine like cannon-es, but you will need to know JS to use it. There is an example of general cannon-es usage in the devlogs.
Thank you for your reply. I've seen the examples. Refraining temporarily from 3D platformer (zelda clone) :D
I just used the first person platformer example and added stuff around it like math with a wedge shape to do slopes.
Nice work, have you released a game or demo?
I haven't but I'm not sure where I should/could put one.
How well is instancing in Blender handled in this? I saw it does work, but I can't tell if there's a performance boost or not like would normally be the case.
In general it just treats the instances as an additional mesh to render, so performance would be similar with the same number of polygons between an instanced model and non-instanced model.
Does the prefab option help in this area instead of with only GPU memory?
Prefab will share texture memory between instances, so that will help GPU memory. In general, what is your concern? CPU memory? GPU memory? Performance?
CPU and draw calls mainly.
I see - it won't change that. If we need to draw a poly, there are not many ways to improve that, except by batching. In this case batching for a particular model is most dependent on texture changes, so if you use a texture atlas / single texture for a model, it will be able to batch well.
After installing the add-ons I've tried to open the c3P files, but the same message keeps popping out.
"Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project"
Any idea what may be happening?
I am not sure why, I tried it in an incognito window and installed the latest addon and the Meshpoint example file and it worked fine. When you see this error, can you open the javascript console and see what errors are reported, a screencap will help me see what is happening. Which version of C3 are you using?
The latest, I just updated it.
After a lot of testing I managed to open it, running the browser with administrative rights solved it.
However, it's kind of weird that only your demos presented these issues.
The chrome console sent this kind of errors; I'm leaving those here in case you find it helpful.
Thank you very much for your fast and kind reply, you're the best.
I am glad you got it working. One possible reason is that the addon loads the gltf/glb files during runtime, so the c3 runtime must be able to access them during runtime.
This is an awesome thing to have exist, thanks so much for this.
However a limitation I've run into while experimenting with it to double check what it can achieve, is no matter what I can't seem to get 'backface culling' to work for it (so you can see through the back of something, e.g. to achieve targeted toon outline with black texture+backface culled). I've tested different material settings (using blender), editing the file itself with a text editor (""doubleSided" : true," exists which I thought my be the term required, but true or false changes nothing), all the blend modes, searched through here/the forum thread in-case, etc.
Would appreciate knowing if this is a hard limitation, something I missed, or something that just needs to be parsed from the file in a possible update. Note that this worked without issues in the babylon.js sandbox.
Hi! Thanks for trying out the addon.
One of my goals for this addon is to use the exposed C3 SDK, to keep compatibility with C3 as time goes on. The impact of that is some limitations, due to C3 limitations around how C3 limits changes to the webgl render, fragment and vertex shaders. So, in those regards, material settings in blender are generally not supported. Only simple base color texture is allowed in the render. In addition, C3 does not enable webgl render back face culling (through debug, I have found that it is disabled, just as an experiment I have tried forcing enabling it globally, but other C3 non-3DObject objects are not rendered correctly.) There are also other C3 issues around transparency and ordering.
I imagine it works well in the sandbox, since babylon supports full Metallic-Roughness PBR model.
If you want to share a project, so we can experiment, let me know.
The only _slow_ way I know of doing this, would be doing back face culling on the CPU during render in the addon, which would chew up a lot of CPU perf.
Thanks a lot for the thorough response.
Yeah I imagined it wouldn't be able to do much relative to blender materials, but I also imagined backface culling was about as regular as it gets to the point of expecting that be the default, so was surprised when I couldn't get it.
Yeah that CPU culling doesn't sound like a possible solution to be trading that much performance away. When you say force enabling of back face culling causes issues with non-3DObject objects, does that mean if your project just uses 3DObject's then, this could be an option? Or does your followup comment mean there'd also be further issues introduced if trying to take advantage of 3d located particle sprites too like in your 3DMeshPoint example?
I've got a blender, gltf, and minimal project (the model in it) here. Also a minor and not so minor thing, in the editor the 3d model textures are softened-but it does respect the nearest/point setting when you play the scene so it's not a big problem if that can't be resolved. However also, maybe a limitation of C3, possibly a rendering option though, but the softening of the texture also softens the alpha, and this causes that to pierce through other object as seen here (the left side has separated objects where as the right sides are merged so you can see it pierces per object).
Would be awesome if you could make some advancements with this as backface culling is an especially valuable technique when having to work with a more restrictively performant 3D environment, but I can understand if it might not be possible. Appreciate you're still willing to try and tackle it/have already made attempts.
Here's a hack method - note how it effects the rotating C3 sprite though! I also have not tried with varying the camera, but I imagine it should be ok.

Thanks so much for that :) . Looking at it it seems everything by default for some reason is backfacing (you can see the text rendered, even if on a '2D' layer, disappears with back culling).
It'll be a bit awkward, and limiting/additional steps+triangles required (duplicated and normals flipped) to fix areas of a model you actually need to see both sides of. However for the scope of the game I'm wanting to make, this solution will allow me the end result I'm looking for so thank you very much for that. The trick required to finish the effect is having to flip all 3DObject normals before exporting, that way you can hide the 'front facing' faces (that are now back facing), and hide front-facing instead. This way regular construct objects (at least besides construct 3d shapes) will stay visible.
How do you import a model? I do this:
And I get this:
Does the gltf load properly in https://sandbox.babylonjs.com/ ?
Does it include embedded textures?
If all above is ok, can you please send me your project via file sharing service?
I used Miximo and a convert, but I believe there was a texture.
Did you try it in the Babylon Sandbox?
If you did and it worked, please send me the project, I will take a look.
It didn't work, it just isn't loading the model. I will try making one and putting it in.
bug z-elevation ?
It looks more like the typical difficulty with 3D transparency, sorting, depth buffer and render order. It is not yet easy to solve in C3 (or 3D engines in general!)
Yes. I think too... this is C3 trouble...
You great man. Best regards!!!
Have you considered point light sources (no LightLayer3D) and working with shadows.
I remember the Q3D (banned by Scirra) on the C2. Point light sources worked very correctly there. You had to place them as a 3D model, adjusting the height... but they worked...
I can find
https://www.construct.net/en/free-online-games/animacion-reflejos-3d-30795/play
Thanks for the comments.
Point light sources need more information exposed in the C3 effect SDK, I have requested this, but no response yet.
In general 3DObject is not a full scene 3D addon, it is focused only on the model itself/object itself. I would classify Q3D/three.js/babylon.js as more scene based engines.
Thanks for the answer. I hope that you will be given the data from С3 SDK and everything will work out for you.
Best Regards
cant run 3DMeshPoint ... it says i need remote sprite plugin.
Thanks for the report, will update later today.
Updated 3DMeshPoint to not include remote sprite plugin.
When will the plugin be improved?
Hello. Very very great work!!! I like you.
One question - how fix it )))
This is standard 3Dshape with additive
but. idk... him correct work for other model
This definitely looks like a transparency / depth buffer / render order issue. Is the light cone a 3DObject or a 3DShape? Have you tried placing the light cone on a different layer (probably a higher layer)?
Cool looking art! What kind of game is it?
Hi. I have solved this problem. You need to add Z-elevation. When 2 models are on 1 line, one model overlaps the other. Not mash on one Z-elevation. Center point model in one z-elevations. Model with additive display - removes part of the other model.
p.s.
>> 3DObject or a 3DShape? - any maybe, i/.m use both
But i have new. 2D transparent sprite placed in 3D layer ))) any z-elevation... sprite with any blendmode if z-elevation with "-"
>>Cool looking art! What kind of game is it?
Thank you. my wip.
Transparency is still difficult with C3 and 3D. Need to move to different layers to force render order properly.
I buy this plugin. But Why different color?? original vs my construct
The plug-in only works with diffuse textures (albedo), not bump map, normal map or other texture shaders, I wonder if the model you are using is more complex in terms of textures and shading. Only the diffuse texture will be rendered. Can you share the glb model?
ok I see. Can you tell me how to convert from blender to diffuse texture?
plz your mail. I send to my modeling data
Can you just post the glb via a service like https://sendgb.com ?
I am not a blender expert, but I looked at this video previously about texture baking (it seems pretty complicated, but it got the result.)
Im trying to shoot 3d object missle in fps view, how do I set angle of the model towards look direction with the x angle? Anyone have example???
thinking about getting construct 3 with this. can this run about 100 low poly animated models on screen without lagging? ive tested with the 3d cubes only and that was fine.
it can run 100 low poly models, how ever you'll experience lag while working on the game. but when the game is exported most of the lag will clear up. I also recommend adding an optimizer script like this help reduce lag.
thx bro ill use that, does setting object visiblility help? or is it only the animation rate that matters
both are important but animation rate costs the most cpu usage. I believe that even if you change the visibility, the animation is still calculated to its fullest so its still best to reduce that to keep smooth gameplay.
Good comments from StarCoffey!
Gracias
ah ok ty!
I am not sure what you mean, can you provide more details?
ah, no it’s not, but that looks really interesting. I imagine you would have to render those as webm or sprite sheet to include in C3.
might be able to with this?i dont own construct 3 yet but will test in the future.i have used effekseer for unity in the past
https://github.com/effekseer/EffekseerForWebGL
webgl demo
https://effekseer.github.io/EffekseerForWebGL/Sample/index.html
Thanks for the pointer. That may help to create a new separate C3 addon, but it will not help 3DObject play this type of animation.
am i doing something wrong? 😅
use regular z setting, not normalized z.
thanks for your hard work。the uv ctrl is real nice,and i hope we can ctrl mesh point，so we can make a man hit 3dobj obj transform at hit point，and ctrl more element like bone，it，must difficult to do it
At some point we’ll get that!
I'm interested in creating 3D games in Construct3 with Minecraft-style graphics, but I'm new to 3D. How do I create the 3D models? i.e. what free tools/formats are best?
You can look at using 3DShape for Minecraft style. 3D models, I suggest looking at tutorials for 3D tools (blender, glb format, etc.)
I love it - but one problem cant apply car behavior? I can accelerate but cant steer? I can also rotate xyz but doesnt update car.movingangle if i do that
Thanks to Dev - creating a sprite and pinning the 3dObject to it did the trick (also put the rotation update in everytick seemed to be more reliable than pin behavior)
You probably should just use an invisible sprite object with car behavior and add the 3D model as a child to it then change its rotations to the angle of the sprite however is appropriate for your game. C3 only has one rotation in 2D that it understands and models have three different rotation values that are unrelated.
Hi, I am new to 3d in construct. Is it difficult to use?
I would recommend trying the built In 3DCamera and 3DShape first to get a feel for how 3D works in C3. After that, come back and check out 3DObject.
works like a charm, so happy I found this <3
one thing though, it seems I cannot rotate an object with actions, I can set angle in properties, but cannot do so with actions.
Even if you add it to a hierarchy so to force its angle, it does not follow, here is a gif I recorded
can this be worked around? I was eager to use this in a project =)
thanks for this addon btw
You are welcome. Have you tried rotate object action?
If that does not work, can you send a link to the project? If you want to DM the project, I am on Construct Community Discord.
thanks for the fast response! when I look for rotate, this is what I see
then if I choose that action, this is what I see
there is move along angle action but it seems to do something else, I uploaded the project here so you can have a look
https://cdn2.pranta.quest/gltfObjectTest.c3p
Can you describe in more detail what you are trying to do with the 3DObject in regards to an angle? I don’t think I understand yet, because I thought rotation would do what you want.
Try this, and see if does what you want:
I was trying to make it have the same rotation as the player, trying that right awa
oh that works, feeling stupid now, 3d rotation tricked my brain lol, thanks
Has anyone figured out an efficient workflow for taking the Synty POLYGON characters, importing non linear animations for them and then exporting them as gltf? I've been trying all night, trying mostly with blender but also trying gltf export plugins in unreal engine that didn't work. I just wanna build up my library of animated characters in .gltf >< not a lot of gltf model packs online except for quaternius
is there an update planned?
Yes, some changes coming.
Is there some way to pin an object to a position on a model? So when the model rotates or moves via animation etc, the object will stay at that same relative position.
No not yet, in fact the gltf format does not have a center point per mesh. I may look at this in the future and if so I’ll probably do average, which will cost some performance.
That's fair. I figured you would have to do something C3 side that would be at the expense of performance to some extent because I've made stuff in Blender and didn't see a way gltf could store it.
It would probably still definitely be a useful feature if used appropriately. Like attaching objects with collision boxes to damage the player if a limb hits them or chain models together maybe.
Currently I'm using the plugin for giant bosses in my first person horror game and some other various things that only it can pull off. Otherwise enemies and stuff are like DOOM billboards. So pinned objects might work fine in that setting.
This is a great plugin though. I've been using this stuff since Construct 2 and I never thought we'd be having full 3D some day even if only cosmetic.
