I have devoted an individual chapter for making the bricks and damaged walls.

I think bump mapping is useless for making good-looking bricks and walls, so I decided to use 3d bricks together with the perfect texture and bump for details like a dirt and parquet.

My technique: I always make the bricks and damaged walls right after texturing, it maybe incredible, but I have never seen a good damaged wall with bricks before.

First, create a simple wall with only a low poly count and with the basic shape of the wall, where the bricks and all the damaged areas will be and then unwrap and make it a texture. After the texturing has started, model the small details by following the texture. When I was finished, I modeled about five low polybricks (so they didn't all look the same) only, about 200 poly. After that I implemented the bricks to the damaged areas following brick texture. I then collapsed the areas with the bricks together and mapped them with the same texture as the wall, and that’s it. I used only poly modeling, mainly paint deformation, not displace.

Here is an animated gif, you can see, that the bricks on the first frame are flat and the wall looks really bad, and on the last frame is all looks ok.

For grass I used this simple plane modeled like a blade.
