URGENT BUG: Meta Avatar v20.3 Library Shader Error (Needs Meta's Attention)
I have been getting the error below in my Unity 2022.3.11f1 project with the Oculus Integration v57, Oculus XR 4.1.1 and v20.3 of the Meta Avatars. I just created a fresh new project and only imported the above and am already getting the same error which indicates it was not my project in particular, but rather a bug in the Meta Avatars Library shader. Looks like sampler3D_float is not supported in this version of Unity based on my limited understanding of shaders. I have included the project where this error is occuring as I am hoping someone on the Meta Avatars team can look into this as it is causing me a lot of issues and crashes when I build.
