Talks And Demos: Building advanced effects in Niagara | Unreal Engine

This tutorial is really great. I was wondering if anyone could expand a bit on the Mesh Reproduction Sprite module and how you can use it on a skeletal mesh that has multiple materials. How do you target one material at a time and build up the entirety of the skeletal mesh with multiple emitters so all materials can show correctly? Is it using the Sampling Regions parameter? Cause I can’t seem to get that to work correctly for me. Any help or guidance would be greatly appreciated.
