Hello, so the question is pretty straight forward, I can’t for the love of god figure out why is this happening…
-I will upload the file bellow, it’s bellow 2MB so if someone can import this for me and then send me the imported asset file, I’d be so thankful!

Also, here is the crash report, or what it said anyways… (Thank you if anyone can help me out <3)

Oh, it doesn’t allow me to upload .abc file type here. Okay I will post it online so you can download if you are willing to help me out, it’s a small file…it should be quick import into Ue if all works fine. Thank you!

Still having same problem, two years later lol. Is there some sort of compression import option for alembics in UE that makes alembics a manageable size to run with?

I think I found the solution:
In my case I had to re-mesh my geometry. some of the faces weren’t triangles nor quads.
