We were extremely excited to finally see Alembic support in Unreal engine. Previously we had written our own custom Alembic importer but it was always a bit buggy and were looking forward to this.
Sadly though at this time, I have tried importing over a dozen different Alembic files and every single one of them has crashed the Unreal editor upon import. I select the file, the import dialog opens up and the list of meshes in the alembic looks correct. I leave everything at the default and hit import, and it crashes.
As best I can tell it is crashing in FStaticMeshRenderData::Cache. Specifically, when it tries to build the distance field data I think. I’m going to try turning off distance field stuff and see if that fixes it or not. Have not done that yet.
