In the example below, I have setup a sequencer that changes mesh during the animation. As seen in the video below, when I manually move the timestamp it works. However, within the sequencer itself when I press play the mesh doesn’t change (nor in Creative Play).
This may be because they’re FN props. Have you tried with imported static meshes? I seem to remember it working.
Either way, still a bug.
Sequencer is referencing an EditiorOnlyStaticMeshComponent in that video. Those are only designed to work in the editor, and not runtime. Can you try it with a regular static mesh?
I wanted to use Fortnite props though, it’s very limiting if it’s only for static meshes.
