Cobblestone - Photogrammetry based Environment Texture

Practicing seam removal for tiling textures I picked another cobblestone surface. Pretty easy to scan but quite tricky to tile as stones are not aligned in straight lines. I believe this is still not the worst tiling case, but was pretty hard compared to the previous one. Have found that manual tiling for textures like that one is a bit like puzzle solving. You need to find matching puzzles and copy them into proper place to make it working as whole. I never enjoyed puzzle solving ;) and it took me about 1 hour to solve that one. Fortunately it is done and works fine.
To capture it I took 41 images, processed them in Photoscan to get 41mln poly model, build LP in ZBrush, baked in SD, removed seams and tweaked in SP, processed final maps in SD and presented in Toolbag :).
