Gravel - Photogrammetry based Environment Texture

Environment Texture of Gravel based on scan Done for practice and to improve my existing pipeline.
In that case I took just 17 images with 18MPx camera using tripod. I generated high poly model with 9 mln polys and used 'Topology' brush in Zbursh to make LowPoly model to bake it later. I used Substance Designer to bake maps and used 'Smart Auto Tile' node to tile them. I also used Substance Designer to make some live PBR tweaks on outputs. Was trying to skip height map cause it was broken instead of fixing it and build one using normal data, but I don't think it was the best solution. Auto Tile Node seems to be the fastest option to and work for non-patterned environment surfaces .. In my opinion node sucks and hopefully Allegorithmic will make the one which is more useful.
