A little trick i did a while back. Triplanar mapping gives you a clean UV layout based on the world position of the vertex/pixel being rendered. This is very useful when greyboxing a level, as you don't need to be concerned with textures stretching - just scale and move boxes to your heart's content.
I decided to add 2 alternative textures to demonstrate how you could use different textures for different projection directions. If you want to blend specular color, power, or whatever with the mask check out some of my tutorials on directional / RGB masking from before - im feeling a bit too lazy today to include it. The blending is pretty good between multiple textures and when applied to curved objects. I have another technique that can be cheaper, but this is the most complete solution i know. Just for fun i reused my moss and dirt textures to make an HD minecraft block.
