Unity XR Simulator Crashing

While working in Unity and using Meta’s XR Simulator, I’ve found that there’s certain instances when it crashes or won’t load. These have caused me countless hours of problem solving so let me outline what I’ve learned below so you don’t have to go through the same thing.

Some of these are likely may be Mac specific as that’s what I work on — And the simulator is newer and more buggy on Mac.

Debug logs in update functions

While testing, occasionally I’ll turn to putting Debug.Log in an script class’s Update method. I’ve found that while this works when running in Unity, it causes the XR Simulator to freeze.

Occlusion Building Blocks

When I have set up Occlusion in my scene using Meta’s Building Blocks, the simulator freezes on load. To get around this, I deactivate those blocks while testing.

Thanks…

I also dissect and speculate on design and development.
