i'm very interested too

thank you for your reply. diffing the scene is a good idea. until now, I had no idea how to even approach the bug hunting, since it seems not connected to any interaction / changes nor code. it is most likely the serialization of scene data. I'll keep you updated and try to reproduce it. I can actually provide the project as it is not super complex and nor confidential.

I feel you, me having the same problem https://developer.apple.com/forums/thread/810868?page=1#871467022 good to know its the timeline. I try to avoid them for now.

seems there are more people having this problem https://developer.apple.com/forums/thread/809712 i have these problems after adding a timeline to the project. hello devs ? any idea ? not using timelines would a downer

yeah, OpacityComponent does not cut it. Would be nice to have more controls over the pixels for nice transitions between 3d content and video content.

you need to apply a videomaterial via swift to your entity https://developer.apple.com/documentation/realitykit/videomaterial

i would be interested too, to modify the videomaterial, in my case, i'd like to manipulate the alpha channel with a texture. it would be cool of we could change the unlying unlit shader of the videomaterial with shadergraph in reality composer pro.
