This is a sci-fi style weapon model that transforms into 3 forms: scythe/scythe/axe/sword.
For VRChat avatars. It works with Expression Menu and Avatar Dynamics.
It is set up with the Standard shader, but includes textures with Metalic, Roughness, and Glossiness output in grayscale for the shaders commonly used in VRC.
A video of the setup can be found in the downloaded Zip file.
Use Avatars 3.0 Manager when placing parameters and expression menus if you don't want your avatar to only have this as a toggle.
