Thanks Guys! Glad you like it.
Working on it the Past few Days to nail down a way to colorize the Texture through BPR Filters. Lots of Trail and Error I finally got it to work with minimal tilling issues on the shaded pass, actually had to zoom in to 200% in Photoshop to see the slight color shift.
So I decided to apply the Textures to the Demo Head in Zbrush, did a quick UV on him putting the seam at the back of his head, adjusted the u and v repeats and Voila, a Crazy Looking Zombie Head. Did a little touch up on the Painting using Cavity and Peaks/Valley Masks. Then Took everything to Substance Painter to throw some Smart Materials on him using the Base Color from Zbrush, did a quick export of the New Maps and sent into Keyshot 6 and applied the Translucent Advanced onto it with the Roughness applied to the Specular channel.
Let me know what you think, am I heading in the Right Direction with it.
Also Download and Try the Textures I used for this Guy and see what you think.
