Comment on Turn off camera in RealityView for iOS?
Can I create a fully immersive space for iOS? It looks like a visionOS-only feature. Background: I am developing an app that works on both Apple Vision Pro and iPhone/iPad. For Apple Vision Pro, the main interaction is in mixed reality, switching to fully immersive VR experience during cut scenes. For iPhone/iPad, the main interaction uses a RealityView with a fixed PerspectiveCamera for a SceneKit-like experience, then switching to fully immersive VR experience during cut scenes.

Comment on Are RealityKit lights expensive?
I was creating a scene (a cafe) in Blender, and I wanted to control the lighting to create a certain mood (e.g., individual lights over tables) - more of a VR experience than an AR experience. Fortunately I ran into this early, so I can adapt. General workflow: model in Blender > [GLB/GLTF file] > "Reality Converter" to add textures > [USDZ file] > into app (where I add lights)

Comment on polygon count vs. triangle count?
Thanks. I created a number of terrain maps of Mars this weekend with a grid of ~320 points on a side (= ~101K squares, 203K triangles). Everything seemed to work fine for a while, but after viewing several models for a while, the frame rate would drop. (It was a LiDAR-based device, which I'm guessing added a lot of its own mesh for occlusion purposes.) I'll do the next batch of terrain models at at a resolution of 224 points on a side to see if that helps. (Way back when I took computer graphics courses, we did everything in triangles. I guess I should keep that in mind.)

Comment on Getting to MeshAnchor.MeshClassification from MeshAnchor?
Thanks! I took a slightly less efficient approach (mainly, so I could understand all the nested data structures), and I could get the results I wanted. For example, I applied occlusion material to .seat (which includes couches) or .floor), so I could get my couch/chairs or floor to appear through the virtual content in mixed reality mode.

Comment on Reality Converter fails to convert FBX on M1 Mac
BTW, if you read the whole thread I referenced, this dependency on older Autodesk software is really a nightmare, and like I said, I'm not sure how to role back to identify exactly which combinations of older packages did the trick for me. I hope Apple has some new & better tools coming out soon.
