Metahumans and level sequencer.. why so painful

Looking for some advice.
I am trying to create a basic level sequence of one of my MetaHumans and I am having so much trouble with additive control rig adjustments.

Basic workflow:

  1. Create level sequence
  2. Drop in my MH (either spawned or direct from map - doesn’t matter which)
  3. Remove control rig from body
  4. Add a nice animation sequence to the “body”
  5. Bake animation to MH control rig
  6. Add additive track to the control rig so I can adjust to animation track to exactly what I want.
  7. ARGGGGGGH… stop removing my additive changes every time I save the level sequence (yes I am keyframing the changes)
  8. Delete all and rinse and repeat 2-7… more arghh…

I simply cannot seem to get the control rig changes to stick.
I also hate how I have to keep enabling the ik contols on the additive every time I want to move ik handles around.

Has anyone successfully created a nice level sequence WITH additively changing the baked animation via the control rig. (A tutorial would be awesome - I have to be doing something wrong).

Thanks in advance…

PS: Epic Games… outside of the above I am LOVING Metahumans, I won’t use CC3 again I don’t think, even despite the early release limitations.

Ok so the plot thickens… it seems that the additive control rig track actually does nothing at all :confused:

I have found that if I bake an animation to the control rig and then add an additive to the control rig (with the little + ) then whenever I adjust IK controls on the additive control rig layer, NONE of the addiditve values change. It seems to only change the top control rig layer (the keyframed layer).

I guess now, has anyone had success with an additive layer on the control rig and how did you get it to change the values and have them stick when saving.

Come on Unreal friends… SURELY someone else has experienced this issue with so many people trying Metahumans.
There must be someone out there that has found the one thing that solves this LOL.

@EpicStaff … maybe someone from your great animation team could chime in here

Are you using UE4 or UE5?

Hey @scottunreal I should probably have mentioned that hey… 4.26.2

I have been working on it more today and I think I might have discovered the problem after days and days… I think I can just manually key the changes at the additive level, my issue appears to be when I have autokeying turned on… which is a pain, but if it is what it is I can at least live with manually keying.
