Quest shaders casting shadows?

Hi, I’m attempting to port a VRChat avatar of mine to Quest. But whenever I try to use VRchat/Mobile shaders this happens

(Using VRChat/Mobile/Toon Lit)

(for reference it’s supposed to look like this)

(Using Unlit/Texture)

Has anyone else encountered this problem?

Note: The same “shadow eyes” thing happens with all VRChat/Mobile shaders and a few unity ones (eg, Particles/Standard Unlit)

Any help is appreciated!

I would check to ensure the model doesn’t have vertex colors in Blender.

Another thing I would check is if those areas of the model has transparency. If they do the mobile shaders will not display them correctly.
