Quote - Actaully, middle gray is the base non displaced color. Black (or darker) displaces inward, and white displaces outward.

NOOOOOOO!

That is other programs. In Poser, black = 0. To produce no displacement, you send a ZERO to the displacment channel.

I have written about this many times. I wrote an extensive thread with many pictures - don't know where that is now.

Red 255 would produce 1/3 displacement. Red 127 would produce 1/6 displacement.

To produce negative displacement, you must send a negative number. THESE ARE NOT COLORS PEOPLE. They are numbers. It just so happens you can "see" numbers between 0 and 1 as gray scale, but you limit your thinking (in fact you muddle your thinking) by insisting that the data is a gray scale image. It is not an image. It is a two-dimensional array of numbers.


Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
