So I've never had to do very advanced UVW mapping since I do ArchVIZ renderings. Mostly everything is a Box UVW map with appropriate sizes. But, I want to take my renderings to the next level with displacement mapping, especially on exterior stone.

First off, how do I keep the corners from having gaps when the displacement map displaces the geometry? Second, how do I make sure the map wraps around the corner correctly? Any kind of tutorial or simple explanation as to how to do this would be greatly appreciated.

An example of what I'm trying to achieve is something like this.

Thanks in advance,
Chris
