I'm working on a project wherein RealityKit for iOS will be used to display 3D files (USDZ) in a real-world environment. The model will also need to animate differently depending on which button is pressed. When using models that are downloaded from various websites or via Apple QuickLook, the code functions well. I can hold the animation in place and click a button to play it. Unfortunately, although the model (through blender) my team provided is animating in SceneKit, it does not play at all when left in the real world, not even when a button is pressed. I checked RealityKit USDZ tool, and found usdz file is not valid, they are not figure out whats wrong. Could you please help me figure out what's wrong with my USDZ file?
