Perfect Tile System - Do you guys want this for the Marketplace?

Mariomguy, you seem to be the man whom might know how to texture my highpoly brick wall. In the pic I have the UV map was just flattened to do a test on frame rate with the Oculus Rift. But when I was in the editor it actually looked good with no tilling happening. now that I have done the UV’s properly, how would I go about doing the random pattern on the bricks with the material.

Here is the pic of the building with the flattened UV

Because I used the concrete grime texture from the starter content and the UV map was just random positioning in 3ds max it gave the bricks in the wall random colors. Any help with this would help in making the lowpoly meshes the same texture pattern.
