$moss enable

Moss shader example, for $moss_texture used xen/moss00_d.

This shader was created during development of Xen for Black Mesa and is designed to simulate presence of moss on surface. Instead of using texture itself for moss, this shader takes color that most of the texture consists of and then applies color to surface according to the parameters specified in .vmt.

Warning: This shader was never used by developers in Black Mesa campaign, may be incomplete and incompatible with other shaders, use carefully.

Todo:  Take the rocks model and materials from the game files and document how this shader works with models.
