Concrete - Photogrammetry based Environment Texture

That capture might look like a piece of cake but it took me months really to find, capture and turn into useful PBR material that type of generic concrete surface
Capture was also quite hard since it was a very windy day and clouds were moving very fast. As you can notice on photoscan preview, at the end of the capture (top corner part of surface) I was caught by the sun and in result got shadows visible on part of reconstructed mesh.
Since the surface was flat and I was in hurry I decided to set the camera's focal length to 24mm. In these lighting conditions and aperture f8, average exposure time was around 1/180 sec. Definitely enough to compensate the wind and monopod stabilisation and get 100% clean and sharp images in result.
Finally I managed to get 75 images which Photoscan turned into 44mln poly model.
Render was done in Marmoset Toolbag using my own HDRI map. For those who havent take them yet, here they are:
