Finally something new!
I have decided to rework my first sand material and on the way of creating a beach sand material, I ended up with some canyon or desert-lile sand material. I could definitely improve the small pebbles or add more finer detail like dried up grass, beetles or anything else that might crawl on there, but in the end I wanted to put the focus on the sand anyway.
