Single Brick
This is a single brick, this allows you to be creative and create piles of bricks the way you want them, you may have an asset of a half knocked down wall, place some bricks on the ground around it to make it look more realistic, you may have to change the material tint colour to make it match the existing wall etc etc.
Like stated above you can change the colour by going to the material editor and changing the tint colour.
