@qbism @toneddu2000 is just a test , i am not using offsetting map or exagerated "specular map", is just a model in the wall. the terrain generator is for the bricks in the wall, so i get the model with ms3d and writing the hieghtmap in gimp

after i optimized the model (reducing poly count ) . the gloss mapping is exagerated and normal mapping is fine i think.
@Seven yeah the light is very near to show the shadows of the bricks, i think this tedious way to make "bricks" is nice to get medieval walls.
@Spike the bricks are of wet stone
