o_0 I ...am going to go wimper now.....I SO wish I could get to those levels.

I have played in zbrush and other then being able to do morphs for v4 etc I got stuck on the painting part. I just couldnt get it to move "beasty" around so I could paint all of him and it just wasnt working. (yes I did come here and ask in the zbrush forum) but it was like greek to me.

I wonder if there is a way to make a deal with the devil for instant knowledge of zbrush....

bottom left there's a download guide also.

You don't half to have zBrush to do this.

You could make multiple renders in any app ,render engine.
Each render engine /Shaders would have something different to offer.

You can layer any set of renders in photoshop ,gimp.

Anyone is capable of this :)
