The material of dry ground/dirt made of scan of dirt with grass patches. So basically, I used a single scan to create 3 different material variations. Fot this one I masked all leafs and grass scrubs and used the ArtEngine to get them replaced with unmasked content.
This way I made a very good dirt material which blends very well with its both other version but also can be used as a generic dry dirt to blend with other dry terrain materials. Surprisingly I didnt expect this material to turn so well.
For those with access, I added this material to my material's library:

Last but not least, I planned to make a quick blending video preview for this material breakdown, which actually has ended up as a short video tutorial. Hope anyone finds this short video form useful and informative:

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
A short video tutorial I made to cover basics of texture blending with these exact materials used as an example:
