Did you do any duplicating of an animation blueprint or retargeting of animations when you imported the mesh?
Run this: r.Shadow.Virtual.Cache.DrawInvalidatingBounds 1
When you move around your mesh and it’s animations play does the volume dynamically resize around the animations or does it seems generally static. I ran into this and found that when I tried to import and retarget stuff to try to reuse some things that for whatever reason it broke something and the bounds were not updating. I reimported the asset and tried again without retargeting and the issue no longer happened with that mesh.
