I’ll have to keep searching, but I am trying to do something like this as well.
I am trying to make a dogs head animate via it’s Anim Montage/Group, at the same time as it’s Tail Group. I can get the Tail to work if the head’s not playing, or vice versa, but not at the same time.
I setup the same flow as above, trying to do the head first, then tail. They both are blending into diff bones as you’d expect. But maybe I need to change the blend depth or something else…
Edit: I figured it out!
I setup the nodes as shown above, but I left the blend depth at 1 for both. WIth the Tail/Lower Body to the left, and Upper body to the right.
The main issue was, I had to setup Groups! They had their own Slots, but were both in the Default Group. So I made a Head/Tail Group and moved the slots into those, and bingo! Now I can blend in the head animations/montages, on-top of a Tail Montage, plus the main body has it’s own Idle/Walk Animation.
