Animation Not Fully Playing in Game, But works in APE

Fanatic:

Ported an animation of this doorway blowing up, and it looks like it's fully working in APE, but when I try it in game, it looks as if half of the wooden shards aren't animated and just appear instantly.





This is my first time working with animations, so apologies if it's an easy fix.

That's the vid I followed at first, and tried the tag_origin fix and didn't seem to work.

Although, if it fully plays in APE with no issues, would it be a problem with MAYA?
