I've attempted to add custom materials to the gmod material tool with some small amount of sucesss ,but..
The materials do not 'work' per say.

When applied to an object they appear invisible. Any help with this would be appreciated.
Any code with this would be appreciated.
The material must be using vertexlitgeneric shader in order to be usable on models.
