Following my written thesis on weather in games, I looked into snow shaders and the material creation process within Unreal Engine 4. Using a pipeline of Substance Designer, Marmoset Toolbag and Unreal Engine 4, I created a shader which works with tessellation, channel packing and masks to create dynamic snow trails. Additionally, I created a system which allows users to place their own assets and textures, allowing them to be affected by the snow and imported into the scene using my shader.
