hi, i use Your outline effect in 3D game, this working with Billboard sprite, but effect looks like this, when background is dont visible or dont exist. You can fix this?
I will take a look at it and see if I can update it, this effect was done before the 3DShape was available, so there might be some limitations due to how 3DShape effects are rendered. This looks like the Fallout 2 remake, which is a great project!
Can you please send me a simple project with this issue? I tried it myself in a simple project using billboard and transparent background and it looked ok, so I imagine that there is something different between our projects that I need to take a look at.
Thanks for the example, this is an interesting and complicated problem based on the C3 3D render and how they have attempted to handle transparency for 3D rendering. It will take some thinking, I don't think it is possible to fix in the shader itself, but there might be a workaround.
Tech details below, with a trace of the C3 rendering.
Some more 3D transparency 'fun', when rendering effects like outline, the first render to an intermediate buffer writes to the depth buffer, but since the outline is not enabled yet, the area of the outline does not write to the z buffer. Later when the effect is rendered into the frame buffer the outline is applied, but the z values from the intermediate render are not set in the outline region (they are 1, max distance). Later when the far background is rendered, even though it should be behind the zombie (and the outline) with a lower z, it renders 'over' the outline at the bottom, because the 'z' is not set for the outline. The outline for around the zombie against the wall works, because the wall is rendered first before the zombie and sets z values, so when the background is rendered later it does not write over the pixels. Whew, hmmm how to fix.
Ah, I think it not an issue of them not getting rendered, it is the issue of the depth value behind the effect outline pixel being 1, so the fog effect goes to the maximum value and the red outline is mixed to the full fog color. I posted this to the C3 forum also, perhaps Scirra devs have an idea about how to handle this.

Android. sprites that use this effect become invisible
Hmm, not sure, can you let me know which type? Android? IOS? Only use WebGL/WebGL2.

Hi, scirra relase new graphics engine in c# called WebGPU, its possible to update your plugin?
I and others are working on automating the porting process, once that is done, I’ll start conversion for my effects.
these are great thanks! Will you be updating them to WebGPU?

Thank you. Your outline effect is best, works well also when i preview game in small window. (Rojohound outline effect have glitches in small window)

i think you should take look at layers

Just bought and it’s a great addon for c3.
great stuff.
Thanks, always interested to see it in use!
Awesome, gonna pick this up when I have some time to experiment with it!
I hope you have fun experimenting.
Another great effect!! Thanks a lot!
Thank you.
