I can rig the model to any skeleton layout that you wish. I would do it with blender, which is compatible with unity in my experience. I can also animate if necessary in a follow-up job.
Relevant Skills and Experience
I have had extensive experience in rigging models for unity3D. Though I've never worked with VRchat directly, I have often modeled, textured, rigged and animated meshes for use in unity.
Proposed Milestones
$25 USD - model rigged
Additional Services Offered
$10 USD - up to 7 animations (10 per 7)
