Free Colorizer Function for UE4

Alireza Khajehali has shared a free colorizer function for Unreal Engine 4 users. The thing will help you set up world space color variation and make scenes look more natural and interesting. 

From large surfaces such as landscapes to smaller objects like rock formations. World space color variation is always the key to make things look more natural and interesting. This function gets your Albedo and outputs parameters to the material instance for you to introduce any sort of color variation to the surface at any scale, using a single RGB Texture Map.
