so I have this animation or whatever to use, how do I go about reverting back to default pose? like when I put in the nodes or whatever for it at the end it changes the pising throughout ykwim, I'll put in a rotation at the end and it'll slowly rotate over the course of the animation, is there a way to like transcribe nodes from the current pose into all the channels or whatever, or is there like a divider mechanic so that it doesn't affect the rest of the animation beforehand? like have pose reverse back to default positions/rotations/sizes without changing the rest of the previous animation?
(I think it's an optifine entity, I just model but it's like a multiplayer server using plugins and stuff)
