To rig creature 3D models for VRChat, align the skeleton with VRChat’s avatar standards—ensuring correct bone hierarchy, weight painting, and compatibility with the VRChat SDK.
Use tools like Blender to build a skeleton matching the creature’s anatomy (e.g., wings for a dragon, extra legs for a monster), then paint weights so each bone moves only the intended model parts. Import into Unity with the VRChat SDK to test movement and fix issues like clipping.
For beginners, start with simple creature designs (e.g., a four-legged animal) and use VRChat’s pre-made avatar rig templates—this helps learn bone placement without overwhelming complexity.
