Hello ,when I import 3DGS pointcloud to unity ,error:"IndexOutOfRangeException: Invalid kernelIndex (0) passed, must be non-negative less than 20. UnityEngine.ComputeShader.GetKernelThreadGroupSizes (System.Int32 kernelIndex, System.UInt32& x, System.UInt32& y, System.UInt32& z) (at <5cd59f99245548bdbfa6531b54530320>:0)
So,how do i solve it? thanks

@yuancaimaiyi I'd need more details to be able to tell what's wrong.

• Which Unity version?
• What OS? (Windows, Mac, Linux)
• Which project are you opening?
• What is your GPU?
• What is the full callstack of that error (it is shown in lower part of Unity Console window when you select that error)

Hi aras-p: Big thanks on your work on this project. I'm experiencing the same problem in this comment.

Platform: Win11, Ubuntu 22.10
project: 0.8.0
GPU: rtx 4070

I'm trying to use this to develop for an Meta Quest 3. Problem occurs when development set for Quest. No issues when running without Quest settings.

Thanks again. I've really enjoyed following this project.

@michnaugh1 that sounds like the editor is in active platform (Android?) that has OpenGL ES (and not Vulkan) setup as the graphics API, i.e. issue #26 -- currently OpenGL or OpenGL ES is not supported.
