How do I find a particular procedural mesh section?

How do I index a procedural mesh’s sections? I’m using getHitResultUnderCursorbyChannel which detects the procedural mesh itself easily enough, but i have tried numerous ways to retrieve the section to no avail. Hit result face index and element index always return -1 and 0 no matter which section i am hovering over, i tried retrieving phys material but that only works if all sections are the same phys material which defeats the purpose. Anyone have any ideas?
