Hello community!
Thought I will share my tutorial about sand accumulation material. The presented method provides cool way how to improve landscape painting with procedural approach. In this article you will learn not only how to create this specific material, but also learn how math can be used for creating advanced shaders.
Tutorial available here: Pseudo realistic sand accumulation material | Unreal Engine 4 blog
Enjoy 
thank you very mutch that very cool to share it with the community ! 
You’re welcome. Hope you will find this tutorial useful
Wow, thanks
this is great, I have needed something very similar thanks!
I love it.
With some modification you think i can use it to snow accumulation effect? It would be awesome.
Snow behaves quite differently as it’s sticky and accumulates on surfaces facing wind. You could modify this material to achieve desired result quite easily.
Back in a day I made in UDK a snow material that accumulates on objects. At some point I might port it into UE4
Very Awesome! Keep making cool tutorials!
