Is there a new way to control VRC avatar dance?

I want to use osc to control avatar skeleton rotation.
such as “Hips, x, y, z, w”.
Is it possible?
Is it possible that, I write my C# and attach it to VRC prefard. and let my C# use animator to control avatar dance?

Hey. Well not those directly, but if you go to the osc documentation page for vrchat, you can use osc parameters to control the input and tracker controllers. That way you can manipulate them with your c# code. If you have a premade animations, you can also just trigger it remotely with osc while it being saved in the avatar.
