Excess Material Slots Created on Alembic Import

Development Character & Animation

I am trying to import an alembic file from Blender to Unreal as a skeletal mesh. The model is an animated fractured mesh that has many pieces. Everything seems to be working fine except that I have a material slot for every piece in UE (there are 64 pieces). I can’t seem to be able to delete the slots (they are grayed out) in the skeletal mesh editor. My experience with skeletal mesh editing is very limited so there might be something I’m just missing.

In Blender, all the pieces use the same material and they are parented to an empty object. I can’t join them, because that would ruin the animation.

I have tried different export/import options (such as merge meshes) but haven’t found anything that would do the trick.

What should I do? I am not sure if I’m doing something wrong in UE or Blender (or both?).

Desperate bump. :no_mouth:

What I ended up doing is opening the skeletal mesh editor and in LOD settings manually setting each of the components to use the same material slots. There were 64 components so I also got a chance to think about my life and where it’s going. After that I was able to delete the excess material slots.

If anyone knows a more optimal solution I would be very grateful!
