Character on left, VertexLitGeneric on right.

Character is a Vertex shader available in Counter-Strike: Global Offensive. Shares most generic parameters of VertexLitGeneric. It takes advantage of mask textures to tune rimlighting, phong shading and other parameters.

Tip:It might be a good idea to look at Valve vmts of new Player Models inside the vpk files, to get better understanding how to structure your Character shader vmt.
