rShaders sand is a procedural shader able to create realistic or fantasy desert environment or surfaces with sand like dunes or beach..
It can be used alone or in a sub-material channel to achieve complex effects like natural environment with desert area and normal ground area with plants, rocks etc.
In general parameters you can find features to control grain size, brightness, contrast and saturation to powerfully controls sand color. Artists can find two added sand layer to create better look for the sand texture, so he can add custom bitmap/procedural maps or use the internal sand editor to create custom sand textures.
User can controls light interaction between environment lighting and sand surface. Complete features controls specularity, simulate grainy specular, sun reflectance and light diffusion.
Bump features allows users to controls amount and visibility with 3 different bump layers, (custom bump map, sand editor bump and internal grain bump).
The shader has the possibility to activate a custom displacement map given by the user, or use the internal dune displacement features.
