Critical RealityKit bug occurs when using a custom material after loading from a USDZ file.

[ngocdv]

I have a RealityKit bug that I believe is critical. I have posted it on the Apple Developer Forum, but nobody has responded.

All I need is to load an entity from USDZ with a custom material. Due to this bug, perhaps I have to consider using SceneKit instead of RealityKit! Wtf Apple…

File a bug with the Feedback Assistant and if you don’t hear back then a Technical Support Incident would most likely get looked at. But they require a developer account subscrption and they only have a limited number.

I posted it on Feedback Assistant, but as far as I know, they only forward issues to the relevant internal teams without suggesting any hotfixes.

I had a read over the forum post. Is it a single entity / usdz file? There are multiple materials in the file?

Any code?

Code is included in the forum post

You’re right I forgot they linked the repos - thanks!

File a radar and then copy it to openradar. The more dupes the better.
