Oh, I thought it would be fairly obvious, but that may just be because I'm an idiot.

I'm referring specifically to the center area of the map where I endeavored to overcome my rampant OCD need for textures to map logically by cutting and splicing brick textures so that they follow the walls in a "realistic" way, rather than just be one tiling texture overlay that has no regard for direction of the surface, etc.

It's an agonizingly boring process, and unfortunately the amount I got done there was the result of like, two days of on-and-off work which was mostly me trying to solve stupid problems like the fact that most of the wall textures sit like, 2 pixels lower than the grid line even though all my walls should be perfectly even...

But yeah, that's what I was trying to achieve. The black walls are the same as they were in every other iteration, just with their texture overlay turned off. Very much NOT the look I want.
