Ayooooo, this is a Unity Editor tool designed specifically for VRChat's new PhysBone system.
Currently, VRChat has not implemented a method to reset your avatars' PhysBones if they have been posed - this system remedies that by automatically generating everything you need to reset your PhysBones with a click of a button!
See the second thumbnail for an explanation.
Download Av3Manager to assist with merging your Animators and Menus!
