[Niagara] For mesh reproduction, is there a way to get the coords of a specific triangle?

The content example for mesh reproduction in Niagara gets the random coordinates for a given particle. This would be good for an erratic-looking effect, but I’m more interested in making sure that each triangle gets one or more particles, for a full reproduction. There doesn’t seem to be a function available to look up coordinates by triangle index, however, so I’m not sure how to achieve it.

Would “MeshTriCoordinate Read” do this? It takes a ParamMap and outputs Tris and Bary Coords. Is the idea that the output triangle will increment as each particle is processed?
