so ive created concrete tiles using floor generator and as you may know when applying the materials, it gets assigned to each individual tile. what ive been trying to do is that i want a concrete base for the tiles, and a partially dirty coat on top for lower tiles. like the image below :
in the picture below you can see that the dirty coat is assigned to every single tile, i dont want that :
i wanna apply an overall texture to those tiles. any tips guys ?
