After carefully sidestepping the unexploded bombs lying around this thread, I want to give my opinion about the black background thing again. Here is an example picture to illustrate:
This is an example of painted vs. non-painted.
On the left is a default black Zbrush background. On the right, I first brushed on a layer of white, then more carefully filled in black. It is indeed different from the left.
So in my opinion ( ;)), this is a very valid tip. Use or don’t use… at your own risk.
BTW, Belleski, I think you may mean the Pixolator image with the Golden Idle Tutorial Script.
