Version 2.34.0 includes a new property for 3DObject - worker animation! Now the CPU work for animating complex models can be done on a separate thread/CPU from the main C3 runtime thread, allowing for more complex models to be animated while keeps a nice 60fps.

This is an experimental feature, so please give feedback on how it works in your case.

Current recommendations for animation worker mode:

  • Only enable for 3DObject models which are higher poly count (500+ polygons)
  • Only enable for animated models
  • Use a lower frame rate for the animation (e.g. 30fps, 20 fps)
    • Set animation rate after model is loaded, using the on loaded ACE

In one example on a desktop PC, I can get 2-3X more models animating at 60fps when using worker animation, compared to not using worker animation. 

Happy Holidays!

Awesome gift :D .
Regrettably though I can't get this to work, even with the GLBExample-2-14-1 file. When ticking worker animation, the model doesn't show up.

Errors appear in console (they don't show if the F12 debug starts open)
"Uncaught ReferenceError: target is not defined
    at updateAnimation
    at updateAnimationPolygons
    at MessagePort.OnMessage"

I can get it to show if I click the 'pause' button, but can't get it to start playing any animations. Is there more setup required? (Made sure project worker mode was turned on too)

Thanks for the bug report, I appreciate it. Based on this report, I have found that for worker animation, there is a currently a bug with animation blending. For now set animation blending to 0 for worker animation. I will work on a fix for this.
