Material with procedural brick map in Refectance 0 map slot.
The row are not the same measure, and the distribution of brick is bad.
Sorry for mi bad english.

Hi Carlos,

The only strange thing I see is that the color of one of the thin bricks should be blue instead of red according to the material preview you are showing.

I understand it may not be very intuitive at first sight, specially the first two options. Brick width and Brick height are in fact it's width and height but in UV coordinates (the values range from 0 to 1), so if you type 0,4 for the brick height, you'll get 2.5 bricks in height (disregarding mortar thickness) 0,4 + 0,4 + 0,2 = 1 and that will repeat beyond the UV projector.

If you want to have the whole cube covered with bricks without a visible repeating pattern you should make the UVs cover the whole cube (9x9) and then make smaller bricks (divide by nine if you want them to have the same proportion)

Let me know if it helped.

Fernando

Thank you very much for the help. In Maxwell doc it is not very clear.
