I’m experiencing a similar issue. It’s not a fundamental solution, but I wanted to share a workaround that worked for me. I found that when running the Sequencer with the PIE button, the AnimSequence with Kawaii Physics applied plays automatically.
- Create a “Level Sequence Actor” in the level and assign your working sequence to this actor. In the actor’s options, check “Playback > PlaybackSettings > AutoPlay.”
- Remove the animation sequence from the sequencer if it’s registered, and instead, play the AnimSequence from the animation blueprint that uses Kawaii Physics.
- Press the PIE (Play In Editor) button.
- The sequence should play automatically, and the animation blueprint (along with the connected Kawaii Physics) will function correctly.
If the sequence doesn’t auto-play after step 3, try adding a “Camera Cut” track in the sequencer and bind the CineCamera to the Camera Cut track.
