Animation not playing in the main window

Hi , I am new to UEFN, I put in an animation just to test, it plays fine in the Preview window, but not in the main realtime window, even though active is checked on for the track…any ideas?

This may be a viewport/editor issue rather than the animation itself. Since it works in Preview, check that the main viewport is using the same Level Sequence/animation instance and that the sequence is actually playing there.

Also try:

  • Scrub the timeline manually to confirm the animation keys are visible.

  • Check that the correct Skeletal Mesh Actor is assigned to the animation track.

  • Make sure the track and section are not muted, disabled, or outside the active playback range.

  • Stop and restart the preview, then refresh/reopen the level if needed.

If it still happens, a screenshot of the Sequencer track and the main viewport would help identify whether it is a playback, binding, or viewport issue.
