For people that have Sinema4D and Photoshop it is easy to bake bump maps to textures.
First make a simple brick texture like this :
Save this texture and then desaturate the texture and invert it, then you have a texture like this :
In Sinema4D, make a single plane, and make a material with the Color texture of the brick
And the bump texture of the desaturate texture, make the bump texture 120% strong.
Then bake a texture named surface Color, and the result is this :
Maybe some people can use this
