Compacted Gravel - Photogrammetry based Environment Material
A material of compacted gravel. This one was captured using full cross polarisation approach. The surface itself was captured nearby to this one 'https://www.artstation.com/artwork/YeXnXw'. It ispretty similar but gravel is slightly bigger and its surface cleaner and more exposed. The idea behind this capture to create a set of materials which can blend when used together very nicely. I used my standard material workflow which can be found on my youtube channel:

Since I am pretty happy with this material, I have added it to my environmental materials library on gumroad:

as 'gb_gravel294'. With this one added, the library contains 72 seamless scan based 4k environment materials.
Cheers!
