Thank you for responding! For my particular scene, my character is an alembic geometry cache element and does not posses a skeleton, therefore I cannot rely on the pills for collision interactions. To be more specific, I would like for my characters hands or clothes to be able to collide with the groom. I am using a marketplace plugin (GeometryCacheCollision in Code Plugins - UE Marketplace) that generates a collision mesh based on the geometry that the alembic file possesses. I am fairly sure the plugin is working as intended, as when I check the “show collisions” box to see if they’re present, they’re glowing blue hue affirms me that the collision mesh is indeed there. To simplify the testing I spawned a simple sphere and generated a collision mesh, but that didn’t seem to work either. As for my specific scene, the physics isn’t totally necessary as both characters I have tested have short hair, but my fear is that later on down the line when I have to render a character with long hair that drapes over their shoulders, it will clip through their clothes or body.
