Mountain, snow and river / Unreal Engine 4 ///

I realized this environment by creating a material that I instantiated in order to very quickly modify the soil materials. It suffices to slide the base color the roughness the normal ... here snow, and the environment is updated ... then with 2 instantiated parameters also we can vary the level of snow / the tessellation is also integrated in the material to give more volume, the result is nice !!! I also used Megascans and the river plugin from Unreal Engine 4. /// :)
