I like the story for the image. Have you tried using a strata shader for the contours?
Thanks for the comments.
I should now try strata on my object, it may be better suited.
I was determined to learn how to use the contour shader, and after that, the warp shader.
I finally found the problem with my contour redirect. My Displacement Scales were wrong.
( proper scaling seems to be my, "usual culprit", standard problem ).
Only a very small range of power fractal displacement will
work in the redirect. Large amounts like 100 don't show any effect. I'm guessing that because this is being used on a ray traced object, only
a small range of approx. 0.3 to 0.7 will successfully produce visible bump map type changes. Also I wasn't considering that redirecting in X first wasn't very meaningful since I had the contour shader building bands of color that start out completely flat in X and Z, because I have the
use Y for altitude box checked.
This sample Result was not what I was aiming for, but I got a fair imitation of
CORK in one render by Not using Y for altitude in the contour shader and checking smooth edges and setting the smoothing distance fairly low.
I guess what I really am trying to do is to shift color areas and not displace geometry.
