Ahaha, yeah.

I've come rather close to getting what I want, i just dropped the res down low and used basic one color textures. Only problem is that you can't tell where one wall ends and another begins.

For some reason one is brighter than the others, which is good, but the problem is that all the others are the same color and further more indistinguishable.
