VRC mobile shader turns 80% of my model black

Maybe the color texture wasn’t applied as a normal texture on the original material. Can you try to show your original material textures?

made the material from brand new. didn’t convert it from another material. however. it looks completely normal in other shaders.

Vertex colors on the 3d model? Might be able to strip with VRC quest tools GitHub - kurotu/VRCQuestTools: Unity editor extension to support uploading VRChat avatars for Oculus Quest

I saw an option for it but haven’t tried it yet.
