4.26 alembic file import distorts mesh

Hello, I’m having an issue importing an alembic file from blender. I’ve done this before with a fluttering flag without issue, this time I’m bringing in a dangling chain that is bouncing.
This is what it looks like pre-export:

When I import into Unreal using the geometry cache option, it appears and plays back normally, however it’s not holding its shape at all, it looks boxy:

I’ve tried several different variations of the settings on import to no avail. I even tried reimporting the alembic BACK into Blender, and it imports there without any issue.

Thank you,

Any one out there? “Is there a-ny one at all?”
