Control Rig, no evaluation between control float and Curve value

Greetings,

My current setup to drive facial is not blendshapes but Pose assets.
Will trying to drive curves from skeletons by control rig. I got the curve value moving, i can also see the control rig working if i set the value manually.
Also tried to put the blueprint control rig inside my scène and using it inside sequencer. Still nothing.
But the gizmo has no effect on it. I tryp post process , also same construction as Meta Humans. But no effect. Any clue? It’s really strange, seem something is not evaluated but no cue what.

Thank you .

Did you ever figure out what the problem was?

I’m having the same issue.

Thanks
