When joining the world "Idle Cube" by CryoZONE I noticed that I can barely see more than ~1 meter then my view seems to be blocked by a sphere after that point. My theory is the author of this world is using some shader that doesn't play well with rendering on the iOS build of VRChat.
Steps to reproduce:
  1. Open VRChat iOS Beta
  2. Load the world "Idle Cube" by CryoZONE
Device info: iPhone 16 Pro
