Some quick VRC SDK Qs:

- Separate materials require separate skinned mesh? Eg. If I want a shader for skin on the body and another one for the clothing.
- Only the thing the VRC_Avatar component is attached to is uploaded asset-wise? Eg. Can pack multiple avatars in one scene and it'll just compile the one.
- Reasonable overall combined texture resolution? 4k x 4k? For PC, who gives a crap about Quest users.
