Spring Grass - Photogrammetry based Environment Material
The second scan of this year with probably the most tricky environmental surface type to scan - grass. I captured this one with the same, wrong seeting as the previous material I captured, so cross-polarisation set to 45 degree with half glare, and auto exposure without the flash being taken into consideration. Same as the previous one, after some photoediting tweaks turned pretty well, therefore I added it to my material's library:

as 'gb_grass316'
It was also an opportunity to keep practicing with Blender as a ZBrsh replacement. With this one I have learnt a few more useful things, which I plan to share on my youtube channel soon, when presenting modified workflow for low poly creation.
Cheers!

My current photogrammetry workflow used for this capture - as you can see I replaced Zbrush with Blender (more details on my youtube channel soon: https://www.youtube.com/c/GrzegorzBaranArt
Source location - captured space marked with 2 rulers which I also used as a scale reference while defining low poly coverage
Source location - an image taken to get sense of overal grass scale and depth - with my shoe used as a height reference
Metashape - photogrammetry reconstruction based on 192 images
Blender - low poly model alginment for further PBR bake
Substance Designer is still my favourite texture baker as it can handle heavy geometry very reliably.
ArtEngine seam removal - I also used gradient to get rid off very repetetive aerial patches on albedo, height and AO
The material and texture-set was added to my material's library:
