Material $flags and $flags2 parameters control how the material is rendered. $flag can be changed in real-time to allow changes in rendering, but $flags2 is read-only and assists the engine or other code in using the material correctly. Enumerations found in 
public/materialsystem/imaterial.h
The flags can also be set via the .vmt Example:
#Sets the MATERIAL_VAR_VERTEXCOLOR and MATERIAL_VAR_VERTEXALPHA flag
UnlitGeneric
{
$basetexture brick/brickwall003a
$vertexcolor 1
$vertexalpha 1
}
$flags
