Thanks Kypher for your interest,
Basically, I get better results using AUVs for displacement but run into all sorts of problems with bumps and textures (Im using Maya, and usually turn off quadratic sampling to stop AUV seams appearing, which is fine for stills but a little dangerous when rendering animation). For the last image I layed out the UVs so to texture, but the quality of the mesh after rendering is no way near true to the the ZB sculpt and Im getting all sorts of artifacts (unlike the image before).
So it seems to be a UV problem.
Now Im looking into applying 2 UV layouts to my mesh (AUV for disp and Layed out UVs for bump and texture)… but Ive never tried this before, and dont know if its possible. I’m going to do a couple more test first to see if this is the issues.
I will try to get some renders to show the issue a little better.
Thanks again, and apologies for the length response:)
