Pillars and Spacers
I found the tiling and UV Maps pro builder to be to long, and spacious. Without perfect tiles they really show the faults in the tile mapping.
Building offsets in a tile is complex and difficult from photos and images.
As I still think there will be big benefits from photographic images I needed a solution to the long walls.
Of course the answer is pretty simple. Something to break up the long space. 1st attempt will be a conduit or pillar.
This should mean I can simplify the UV textures and use repetition more easily without so many unsightly boundaries.
