Rocks for Uncharted 4 and Uncharted the Lost Legacy
These edge pieces needed to look detailed but also be easy for the character to traverse and shimmy on. They can be flipped upside down for sharper environments such as the caves in The Lost Legacy.
A common workflow that we use for natural elements in Uncharted and The Last of us is to sculpt hipoly meshes and bake those maps down to 1x1 maps and overlay tiling textures.
