Grass - Photogrammetry based Environment Texture

Another approach to capture grass practicing photogrammetry. I failed with that one as hell but have also learnt something.
To compensate wind influence and grass height I decided to increase distance from the ground and set focal length to 24mm .. hoping to cover wider area with less details.
To increase camera's height I used tripod's arm but to avoid shoting tripod's legs I changed shooting angle. I managed to take 58, quite sharp and nice angled shots. I processed them to get 35mln polygon highpoly model and.. have found that mesh looks great from one side but is full of gaps from another one. After I baked texture I realized in every place where was a gap I received blurred shit.
Conclusion? Next time I should set camera more perpendicular to the captured surface. Otherwise -especially when surface is not flat like dry sand - every crazy angled shot should be compensated by mirrored one from the other side. Otherwise even hours of fixing in SP won't do much to save the texture.
