Sequencer: Skeletal Mesh with Control Rig Not Animating (Stays in Bind Pose)

Hi everyone,

I’m facing a frustrating issue with Sequencer and I’m hoping someone can spot what I’m missing. I have a simple Skeletal Mesh (a BB-8 droid) that I want to animate using a Control Rig directly in Sequencer.

The Problem:
When I press Play in Sequencer, the character remains completely static in its bind pose, even though I have keyframes on the Control Rig tracks. If I scrub the timeline, I can see the character correctly posed at each keyframe, but it doesn’t play back the animation.

What I’ve Checked (My Debugging Steps):

  1. The Rig is Correct: My rig was created in Blender and works as expected. The hierarchy is simple: Root > Body_Bone / Head_Bone.

  2. The Control Rig Works: I’ve created a Control Rig (CR_BB8) with controls for each bone. If I open the Control Rig editor and manipulate the controls, the preview mesh animates perfectly. This confirms the Control Rig itself is set up correctly.

  3. Sequencer Setup:

  • I’ve created a new, clean Level Sequence.

  • I added the Skeletal Mesh actor to the Sequencer.

  • I deleted the default Animation track.

  • I added the Control Rig track and assigned my CR_BB8 asset. The control tracks (Root_ctrl, body_bone_ctrl, CTRL_head_ctrl) appear correctly.

  1. Keyframing: I can set keyframes on the control tracks using the ‘S’ key. The keyframes appear on the timeline.

  2. Troubleshooting I’ve Tried So Far (and didn’t work):

  • Setting the actor track’s “When Finished” property to Keep State (although this option seems to have been removed/changed in recent versions).

  • Re-assigning the actor to the track (Right-click → Assign Actor).

  • Changing the Skeletal Mesh Component’s Animation Mode between “Use Animation Blueprint” and “Use Animation Asset”.

  • Deleting the actor from the scene and the Sequencer and re-creating everything from scratch.

  • Deleting the Intermediate and Saved folders.

I’m using Unreal Engine version [5.6.1].

It feels like I’m missing one final switch to tell the Sequencer to “take over” the actor during playback. Any ideas would be greatly appreciated. Thank you!
