Hi UDN,
I’m using Unreal Engine 5.5 and I have a Sequence Player setup with an Animation Control Rig. I’m trying to animate/drive Control Rig controls at runtime so I can see live pose changes while the game is running for example, dialing an upper-body pose offset (spine/chest/arms) and immediately seeing the impact on the character. I saw a keynote, I think it was during the lego showcase that the dev was showing that being a possibility. Right now, when I run in PIE, all my controllers (and the control rig itself is disappearing.
What I want:
-
While PIE / in-game, adjust a few Control Rig controls (or a “pose” variable) and have the character update live.
-
The goal is “artist-friendly live tuning,” similar to tweaking a pose slider and seeing it instantly on the character.
Questions:
-
What is the recommended way to set Control Rig control values at runtime when the Control Rig is running inside an Animation Blueprint?
-
Are there engine limitations (threading, animation worker threads, evaluation order) that prevent reliably driving Control Rig controls during runtime?
-
If direct control access isn’t supported, what’s the best supported alternative to achieve live pose tuning?
Context: Character uses standard ABP pipeline (state machine + layered blend per bone for upper body).
Thanks!
