One of the many materials I created for Endzone 2. The simulation was made inside Houdini, using the Game Development Toolset for autotiling distributed Meshes. The mesh was then exported into Designer for Baking and has been procedurally textured after and also got some more tweaks and aging passes inside the Graph. Finally I blended the simulation with a Gravel Material I grabbed from Megascans to embedd it better for the intended use in Endzone 2.
The textures in-game are at a resolution of 1K, while the renders were made at 4K.

Houdini is a really powerful tool and actually the only one of all that I tried, that makes simulation not only easy, but is also fast and precise.
