At the moment, it includes two different versions: the 3.0 Experimental version and the 2.1 Classic version, which differ in design but have the same functionality.
Version 3.0 is still in development, so more animations and textures will be added in the future.
The wings were tested in Unity versions 2019 and 2022.
Animations, menu and parent to Spine bone will be automatically added through the VRC Fury plugin during avatar upload.
After that, you should see a new menu in the Expression Menu called "Wings Control"for 2.1 or "Webbed Wings 3.0e" for 3.0, where you can toggle the wings on and off and control them using a radial menu.
