Chiharu, a 3D artist who focuses on VR characters, presented a nice hand rig they made for a new chibi model.
The cute Blender character is obviously plumper than what we've seen from the artist before, and this volume looks natural with the rig.
"I have inserted one twist bone each into the forearm and upper arm with 50% follow-up, which is a popular technique often used in [VRChat] avatars," Chiharu shared.
