@gster; Yes i have zbrush3, but haven't got 2 anymore. But the problem is that when i export the displacementmap from zbrush into photoshop i get some colorvariations in the backgroundcolor(i've attached an image and exagerated the effect, for display purpose), which are giving an additional bump. I just want to know how to fix this, before i move on. And thanks for thinking along with me
