Problem with import alembic animation


I’ve got two problems.

I’m trying to import alembic animation to Unreal Engine. After that mesh looks like distorted.
On the image left is fbx, right is alembic.

I exported animation from Blender and 3ds Max, both looks good but not in Unreal. What am I doing wrong ?

My full project saved in abc has only 90MB, but importing to 5% took my computer 3 hours and used all 64GB RAM… Importing seems to have no end. Maybe there is something in the settings what can solve the problem.

Both bugs are in version 4.27 and 5ea. Please help :slight_smile:
