I have nearly finished making the tilable walkway floor. Would have finished it yday but Zbrush was being a bitch with its undeveloped Clip Tool. Had to figure out how to cut my floors without loosing the inbetween polys. Finally I managed to pull it off and found a way around it. Took me some time to do that.
Here is the Zbrush render
... and a low poly with the maps baked on and a temporary texture
For this I have created a specific mesh so that I can flip some polygons for less repetition. The whole mesh also works better with lightmapping.
