Hi,Has anyone been able to get the Mental Ray vector displacement shader to work with tangent vector displacement maps coming from Zbrush ?
The diagnostic file tells me I should use a FlipandSwitch setting of 10, but that only results in chewing gum : https://dl.dropbox.com/u/4271217/mentalvec_tangent.jpg
I tried switching color channels in the render tree, and different tangent evaluation modes in Zbrush, but no cigar so far.
Thanks, - Ronald
