Tip:
VRAD has a -dumppropmaps option, which will create external TGA versions of the generated static prop lightmaps which can be converted to VTF and manually defined as a $lightmap.

$lightmap is a material shader parameter available in Source 2013 Multiplayer and 
Garry's Mod for VertexLitGeneric. It defines a lightmap to be used to light the MDL model's material, instead of the per-vertex lighting used by prop_static or point lighting used by other models.
This parameter does not usually need to be added manually, as VRAD will generate model lightmaps automatically if generatelightmaps is enabled for the prop_static and -StaticPropLighting is enabled in VRAD. Nonetheless, it can still be added manually, such as for using a lightmap on a prop_dynamic, or if a prop_static has multiple materials (as VRAD can only generate lightmaps for the first material.
Tip: VRAD has a -dumppropmaps option, which will create external TGA versions of the generated static prop lightmaps which can be converted to VTF and manually defined as a $lightmap.
Todo: What about converting static prop lightmaps from already-compiled maps? They are stored as PPL files, which have a slightly different header from VTF or TGA.
