Quote - @ BB, seems I had it bass ackward but I know there's a real quick and simple way to get the blender node to do what fibbits wanted.  Not being at my Poser box, I was working from memory.  Oh well. :)

@ fibbits.  I tried my best from memory.  Couldn't post a screen shot, else I would have. 

Well here's how to do it with a Blender, but again it is overkill.

Input_1 = black and nothing plugged in

Input_2 = displacement map

Blending = 1 and plug in the mask

Recall Blender(a, b, f) = (1-f)a + fb

So Blender(black, displacement, mask)

You get:

(1-mask)*0 + displacement * mask

This is the same as:

displacement * mask

because the first term is 0. But why bother?

I know you guys don't care for the math, but if you were giving directions on how to turn left, I expect you'd suggest three right turns. giggle The math of multiplication with 1 or 0 is really fundamental - stop pretending it is hard.
