I’m not sure about performance trade offs or anything. The point of this tool is for using the static mesh in a particle system. If you’re importing the Alembic file as a static mesh (not as skeletal or a geo cache) I’m assuming it would be similar. This is all driven by textures in the meshes material though which could have parameters exposed in cascade and or blueprint. I’m not very familiar with using the alembic format though so I don’t know if you could achieve similar results.
