rough wall texture with smooth lines?

Hi this is my first post on the site so if a break any cardinal rules or am posting in the wrong area please let me know.

I was wondering what would be the best way to make a stone wall texture were the individual bricks are very rough and jagged but the lines between remain smooth. like the walls of a Wal - Mart.

I’d set one material for the bricks and one for the lines and have the one for the bricks have a stucci texture, probably wall in, set to Nor. If you need a better explanation, just ask!

Better make it a clouds texture, you can have much more detail as you can set the depth of the noise. Stucci is like noise depth = 0, rough surfaces typically have higher frequency detail than that.
