Hello, I just installed Ornatrix yesterday and still watching tutorials, so sorry if this is really beginner question.

When I apply the UDIM(Mari) maps to distribution multiplier in HairFromGuides, fur in viewport decreases a lot, so I need to increase render count like 50000000.  Without the maps, 100000 hair can cover entire polygon.  Am I doing something wrong or is this how it should work?

Also, do the distribution maps only take 8bit jpg?  I tried to use 16bit tiff or exr, but Ornatrix gave me an error message and shut down Maya.

I've attached my scene (Maya 2017) and distribution maps (jpg) to this thread.

Thank you very much.
