Thank you! 
@_cDub - First of all I’m using camera, that’s the most important tool 
Next is just processing the photos, baking maps and so on…
@SlinkyMuffins - I planned to do them anyway, but I think it will be around January, when I get new camera, meanwhile you can check out freshly uploaded Ground Materials (link below). I already tried Marketplace but I got response that there’s no need for more materials, so I put them on Unity AssetStore first, and recently discovered Gumroad
@Stevelois - You’re welcome, there will be more FREE stuff in future too, so come back in some time 
I’ve just uploaded one of my best selling Material pack on Unity AssetStore, I hope you’ll like it as well Ground/Dirt, these ones are paid, sorry 
But you won’t be dissapointed, and all money will go to buy decent DSLR camera, so I’ll make even more and much better stuff You can easily change color in GIMP/Photoshop to make it desert/African savanna terrains!
Here’s how they look with DX11 on default spheres:
