Since there was a summer in UK last week and sun dried the grass I used an opportunity and captured it.
As new release of substance brings new nodes I used one: to get more control over the baked and tiled normal map I introduced new 'Normal Intensity' node into substance graph I usually use to generate final results. I set it to +20% but since it needs a bit more testing I didn't replace the file in my tutorial yet.
To capture this one I used tripod with the Camera's focal length set to 35mm and I took 179 images.
Next I used Photoscan to processed them into 135mln dense highpoly model but since FBX struggles with anything above 67mln I trimmed useless edges and decimated whats left to 67mln.
Still not happy with this one but it is also not as bad. So another approach and still didn't manage to capture a grass texture I am super happy with :) .. maybe next time.

This is my photogrammetry workflow I follow. (More details: https://www.artstation.com/artwork/K0PYG)
