Eye Purupuru | Wobbly Eyes When Blinking [VRChat / VRoid]

Eye Purupuru is a Unity Editor tool for VRChat avatars that makes the irises wobble naturally when the avatar blinks.

The wobble automatically pauses during winks or closed-eye expressions, then resumes when the eyes open again.

✅ Tested Compatibility

• VRoid-derived VRM0.x avatars

• VRoid-derived VRM1.0 avatars

• Avatars where the iris can be isolated as a separate Material / SubMesh

Some avatars with merged eye and face geometry may not be supported.

If the iris cannot be detected automatically, you can select the Material Slot manually.
