Only after seeing this now, thanks very much.
One issue I'm having is having to use really low values in the nm amount. Like 0.01 min and 0.02 in max with noise as map in this example at value 5. Whereas this should be 500000 / 1000000. The limit you have here is 3000.
I wanted have .5mm to 1mm.
BTW> My max is setup with cm as system units.
Happy with the results though. :]
