Initially the issue was with exporting baked physics anims, but now it shouldn’t be a problem with Alembic format.
I use Blender and fracturing tools aren’t great there. Plus whatever pieces of my scene I made in Blender aren’t in 1:1 scale, so it’s gonna be pain to make sure scale in Blender matches to UE4 to simulate and export properly.
So doing all that in UE4 would make things so much easier and more streamlined.
