Bricks and Blocks
by Philipk
I felt the bakes came out a bit flat if I am to have a more rough looking stone wall, so once again I went into ZBrush, dragged out a plane and used the "Layer Brush" with the "Spray" setting together with the "Projection Master" to quickly create a rough surface.
When baked out to a plane it looks like this. I can now use this as an overlay on my wall and can control the general roughness very easily on them by just altering the opacity on this overlay.
I made the diffuse by having a very simple base layer of some beige color and subtle details, I added another variation layer on to masked with the ambient occlusion map leveled and some other more subtle details. I made the seams more sandy, also masking this layer out with the ambient occlusion map inverted and then some hand painting around a couple of bricks. Finally I added some brightness variation to my stones in a separate overlay layer.
The final maps with the normal map using the overlays seen above. The diffuse is a bit color and contrast adjusted, but you really get most of the diffuse done from just the ambient occlusion bake.
In the specular and glossiness maps I darkened the seams and put an "Outer Glow" using a dark color and setting it to "Multiply" to get some rougher edges. I also kept the specular pretty contrasted.
The end result with all maps applied.
