Already being used in a production setting, Layered Landscapes is an innovative and unique approach to the difficult task of Texturing landscapes. It is a one stop solution for all of your projects due to it's efficiency, easy customization, and intuitive use.
Using the Experimental "layered" materials feature of UE4, Layered Landscapes uniquely allows the user to modify the number of layers the landscape makes use of, directly in the material instance, which makes it highly flexible.
There is also a new approach to landscape grass. With each layer having density controls for each grasstype, which saves a lot of iteration time, and makes it easy to entirely change the look of a biome with a flew drags of a slider.
Layered Landscapes will be on the Unreal Marketplace soon.
