I've searched everywhere for tuts and such on this subject, but everything I find is either done in P5 and out dated or it just doesn't work.  I've followed a bunch of tips and such, but I just can't seem to make displacement maps work, they don't show up in a final render even though the preview in the mat lab shows it, what am I doing wrong and/or how do I make it work?

Have you looked at that thread? There is a section called "How Do I" that covers displacement maps too.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi

If you have connected a map to the displacement channel, the displacement should show up. Have you enabled displacement in the FireFly-render settings? The default render setting disable displacement.

ooo, and here I thought black and white were mainly for trans maps, awesome :D

And watch out for %50Gray, as it will still cause movement; which is what that Math Function neutralizes.  Actually the Math_Functions should be 1, and -1; rather than 1, and -.5.

No! Careful.

The numerical value of mid-gray is .5. That's why we subtract .5 - so that mid-gray equals zero.

Perhaps you wanted 2 and -1? So that WHITE = 1x and BLACK = -1x?

That would work.

Then a .2 in the Displacement field would be exactly .2 inches when you have WHITE and BLACK.

Zbrush makes really nice displacement maps, if you want to get into modeling/sculpting.
