Moss Shader (UE4)

A dynamic moss material created for a recent forest scene in Unreal. My goal was to create a nice dimensional moss that softly captures light and helps tie the scene together. I experimented with a variety of methods, including the layered mesh technique used in Ryse and painting moss chunks using the foliage brush, but this gave me the best results. The Fuzzy Shading and Fresnel nodes were great for getting that soft mossy feel. Textures created in Substance Designer.
