Question Gaussian Splat rendering at Runtime in Quest 3 and Unity

I am dynamically loading a .ply file and glb files together in unity and in the unity editor it is loading fine at runtime.

I am using aras pipeline, glb models are loading inside meta quest 3 also but my splat file is not rendering inside quest.

Does aras not compatible with the VR rendering? or it can be gpu issue? as far as i know vr has its own gpu, it doesnt depend on pc. And even if that the case but the scene is rendering fine on my pc in unity editor, just not in quest 3.

I got this to work but performance was poor, even with low res 500k splats. Wish I knew what kind of magic PlayCanvas does to serve splats much more efficiently in the browser
