//This file contains base material from which other materials can inherit. While optional, it's very, very much encouraged that all materials inherit from these.
//By inheriting any of these materials the material will automatically get support for shadows, LOD, minimap etc.
//Also note that these material represents the most common combinations (for example "/dural/base/simple/nonculled/alphablended" which is a simple material, non culled and with alpha blending).
//However, it's very much possible to extend the base materials in the final material, for example adding alpha rejection to the aforementioned one.
