It's called color griffin because you can change its color via rig for fun color combinations! If that isn't enough, it should be easy to create your own feather textures, since they're all in 1 giant texture, no UDIMs. Other parts of the model DO use UDIMs though.

Includes:

• Blend file with rigged griffin, packed textures, and Rig UI (Blender 4.5 LTS) (651MB)
