>PhysBones is a set of components that lets you add secondary motion to avatars.
>Secondary motion lets parts of your avatar move given some physical parameters, making avatars feel much more real and dynamic with little effort. PhysBones can be used to animate hair, tails, ears, clothing, and much, much more.
>PhysBones: A free, direct and significantly more performant (we’re talking roughly a 12–20x improvement) replacement for Dynamic bones in VRChat that will be included with our SDK. Additionally, PhysBones allows touching, grabbing, and posing bones on your own avatar or on other people’s avatars!
