@starccode Are you able to show us the full log output of your program when it crashes?

Internally, Filament calls Metal API methods on a separate thread which is not set up to report asynchronous failures. If `newTextureWithDescriptor` is returning `nil`, then your app is most likely...

I'm confused, @rawnsley is that link error generated when optimization is set to `MaterialBuilder.Optimization.NONE` or `MaterialBuilder.Optimization.PERFORMANCE`? I'm not sure this has anything to do with filamat-lite.

Yes, I'm able to reproduce with the unchanged sample code (`MaterialBuilder.Optimization.NONE`). If I switch to `MaterialBuilder.Optimization.PERFORMANCE` the error is gone. Unfortunately I think this is a driver bug. Here are...

Just curious, what's the use case for this?

@rohan-nara The `CONFIG_MAX_BONE_COUNT` is [here](https://github.com/google/filament/blob/6ebaad28b36ff3f92f1a84965d9ff21e828730b7/libs/filabridge/include/private/filament/EngineEnums.h#L68). See our [BUILDING.md](https://github.com/google/filament/blob/main/BUILDING.md) instructions on how to build Filament.

This might be the same as #5737.

This is something I'd like to add, but won't be a priority right now. I do plan on increasing the cap on shadow-casting spot lights.

Is there a reason you can't use the Metal backend? We should fix this if it's easy, but we're working to deprecate OpenGL on iOS.
