Happy to finally be able to show this one! Gravel is quite difficult to achieve properly in Substance Designer, so this was a bigger challenge than I expected. Tried quite a few different methods to get the specific "waviness" of gravel, but since I wanted the most flexibility, I went fully with SD. This allows me to control the gravel coverage with just one slider, which is something I really wanted to achieve.
I also wanted to see how well I could blend procedural materials with scanned elements and I think it worked out well. The tree I scanned myself, the leaves are from Megascans and they all blend properly together.
For the pebbles I used several individually scanned heightmaps from Daniel Lindblom's collection to test out combining procedural and scanned elements.
Hope you guys like it!
