The scene contains a 300*300cm wall covered with tiles but you can propagate your own desired tiles and randomize them using corona object replacer, but after distribution you should attach them together, pack the uvs and assign a material by element modifier, set it to random with 10 id counts so the color randomization maps work fine.
