Rock - Photogrammetry based Environment Texture

Another example of already scanned material but processed by Artomatix to remove seams and get all glitches fixed by Artificial Intelligence. Original scan tiled with Substance Painter is here: https://www.artstation.com/artwork/8leGwq
In my opinion the result processed by Artomatix is better to the one I did before and process itself was much faster and less painful. I simply marked with Mask node all areas I wanted to be replaced during reconstruction by AI and executed node.
I removed shadows using gradient removal node but higher values were too destructive I also used on received albedo 'AO Cancellation' node in Substance Designer. I have a feeling that I went a bit to far with the Albedo with shadows removal and it feels a bit unreal now
I belive it is worth to consider leaving some shadows on Albedo for really crazy high differences to keep it photorealistic from the distance but this is just me ;P
