Niagara and Combined Meshes?

Hi, I’m attempting to use a combined mesh with Niagara as separate meshes. I have connected my mesh(es) into a single object in C4D, (and tested that the combined meshes are respected as separate in C4D). I’ve imported with combined meshes = True. But when I set a Niagara mesh renderer to my mesh it spawns it as a single mesh (all the meshes together in 1 blob).

I bought an asset off the marketplace that accomplishes this, so I know it is possible - but the author is not responding to my requests and I’ve had no luck with the UE docs or other online tutorials.

Thanks much!
