Why does my Control Rig pose flicker?

Input pose isn't connected, or Use Animation Pose toggle is off. Without input, Control Rig samples bind pose every alternate frame depending on caching.

Blend weight ramp issues?

Set blend weight to 1.0 in the rig's first frame. Ramping from 0 produces visible blend-in flicker.

Q: Use Animation Pose for IK?

On the Control Rig node in Anim Graph, enable Use Animation Pose for IK. The rig consumes the upstream animation as input rather than starting from rest.

Quick answer: Anim Graph → Control Rig node → Use Animation Pose on. Input pose connected. Blend weight 1 from start.

Foot IK control rig flickers between original pose and adjusted. Input pose wasn’t wired to the Control Rig node, so it alternated.

The Fix

Anim Graph:
  Locomotion StateMachine → Control Rig (FootIK) → Output Pose

Control Rig node Details:
  Use Animation Pose for IK Feet:    true
  Blend Weight:                      1.0
  Init During Compile:               true

Input pose flow keeps consistency. Use Animation Pose flag tells the rig to operate on the upstream pose; without it, rig starts from bind pose every other frame.

Verifying

Foot IK adjusts cleanly per frame. No flicker. Disable Use Animation Pose: flicker returns.

“Use animation pose on. Pose flows. No flicker.”
