Now, I'm off to split some verts and torture Firefly with displacement maps slapped on them...

I don't think I'd ever really tested displacement maps on 'double-sided' faces. So I loaded my 4-vertex/2-face OBJ and tried a couple of things. In each case I applied the same displacement setup to each material, red and blue. 1) First, a fixed displacement of 1", so the faces should end up 2" apart. This looks okay, so displacement is a way round it:

  1. Then something more wiggly. I think the Wave2D node must create output values between -1 and +1 because it causes the two now-wiggly faces to intersect. And the areas where they intersect (i.e. edges between red and blue) aren't 'clean', so the separation distance at these points is probably too small.

The 3Dcheapskate (also available in DAZ and HiveWire3D flavours) occasionally posts sensible stuff. Usually by accident.
And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.
