Baker Xiao Posted August 29, 2017 Share Posted August 29, 2017 During a recent profiling we found that a Scene object is being retained in the heap infinitely even if dispose is called. Apparently the Engine keeps an array of compiledEffects which then has fallback meshes that keep a reference to the scene and that prevented the scene object from being garbage collected. Is this expected? There's about 9MB of stuff that can be wiped out from our pathetic mobile device memory, so definitely hoping there's a way to collect it.

Baker Xiao Posted August 30, 2017 Author Share Posted August 30, 2017 BTW, we tried Engine.releaseEffects(). Unfortunately it doesn't help our case because what we are doing is that we are constructing scene2 when scene1 is about to end. During the construction of scene2, this https://github.com/BabylonJS/Babylon.js/blob/master/src/babylon.engine.ts#L2192 would leak an effect that references scene1 into scene2 making the whole scene1 object tree retained in the heap.
