Hi, I have a question about avatars in VRChat. When you’re creating a custom avatar you need something like a PMX or FBX file to assign weights and stuff.

Is there a list of defined bone names anywhere that lists all the bones in the VRchat armature?

e.g. Left Arm is a bone name because I found it out from a video but that person only used like 12 basic bones and I’m wondering if there’s some more to allow for some nicer facial features and things like this?

It’s not really about names technically (from what I know). What vrchat uses is the unity armature object. It’s a “link” that associate specific bones to specific part of a humanoid body. Then vrchat uses that to animate the main bones of the avatar.

I would suggest showing the sample avatar you can find in unity through the vrc sdk to show the armature structure, but you can always select the armature object and configure the bones manually.

Hope it helps.
