So I had this idea to take a semi-tillable image and use the distort map to make a building
Check the cap.

Its close to what I was wanting to do, but to get the displacement right, I'll need several more rows.
The question is, is it worth it? I mean I can either draw a sprite up, or figure out all the math, etc involved with this, but in all honesty its still going to take up about the same amount of resources.
With one slight advantage to drawing it, and then using a height map on that, cause I'm pretty sure I couldn't use a distort map like in the cap and then use z height on that.
