I’ve seem to have hit a dead end. Can’t fix the shaders around the eyes and choker, despite deleting transparent meshes then exporting from Vroid, fixing avatar with CATS and all that on blender, then changing from Transparent to Cutout in Blender, and shaders to VRChat/Mobile/Toon Lit, the problem still persists.
Now with the rigging, I’ve changed it from generic to humanoid, as you can see in the attached image. I am trying to upload this to Quest 2.
If you google ‘vrchat toon shader alpha clip’, you’ll see that alpha clipping/transparency is not supported on mobile shaders. So use other shaders or make the eye brows etc a more detailed mesh instead of a square mesh with alpha texture.
For the animation, if you google ‘vrchat humanoid rig animation’ you find guides and docs for it
