Sparse Grass Patches - Photogrammetry based Environment Material
I used this scan as base for 3 complementary materials with different coverage of grass patches each - so they blend well together to reduce their visual repetition.
This is also the first time I used Blender to test and render the final material preview. Marmoset Toolbag isnt bad, and it is significantly faster when it comes to render on my old GF1080Ti graphics card, but honestly somehow I prefer the result I managed to get with Blender.
I still didn't decide to drop Marmoset Toolbag totally, but so far it appears to be the second app in my photogrammetry workflow to be replaced with Blender :/
Since I am very happy with this material, I added it to my material's library:

PBR preview: Albedo / Normal / Height / Roughness / Ambient Occlusion
My current photogrammetry workflow used for this capture - as you can see I replaced Zbrush with Blender (more details on my youtube channel: https://www.youtube.com/c/GrzegorzBaranArt
Source location with rulers used as a scale reference
Source location - an image taken as a height reference
Metashape - full 110mln poly dense photogrammetry reconstruction based on 216 32Mpx cross polarised images
Blender - low poly model alignment for further PBR bake - this is one of models used in my video where I shared the process

Photoshop - manual color matching/adjustment based on my PBR Color Reference list. I simply used 2D app to get these values somewhere near to what these values should be:
