What is the replacement for AnimChannel in new 3.3 animation system?

I’m working on learning the new animation system so I can replace the old one entirely in my game, but so far I’ve noticed there is no direct replacement for having multiple AnimChannels.

In this old thread where nehon talked about the animation system while it was in development, I also noticed that he mentions something about playing different animations on separate sets of bones at the same time as not being necessary, I am not sure why he said this because it does seem necessary from my experience, and now I worry the new animation system cannot support this


I need to be able to play a walking animation on the lower half of the body while the upper half of the body plays a separate swinging or flinching animation. Is there some other way to do this with the new animation system?
