Thanks, it kinda works, I had to do a dirty workaround which I found thanks to your code.
My problem was (still kinda is) that when the player dies while blending animation I can't use ragdolls, because it heavily relies on bone functions. What I did is setting pose to 1 and blending back to pose 1, then resetting everything. The downside of this is that the ragdoll now spawns in T-pose, which does not look good.
