Composing individual pillars, walls, and archways, I put together 5 different “sets” during this lesson that made use of material slotting for specific mesh faces.
I tried to keep the stone color palette to 2 or 3 different colors for each set – and then I splashed in a more-spectral, glowing color for the centerpiece at the top of each arch. You have to see where you’re going, after all, so you don’t bump your head on anything rocky 
I’m probably going to tweak these further to add a bit more variation in the material positioning on the blocks – but I figured I’d share my starting point
