$subd is a QC command available in all 
Source games. It is used to mark a model to be tessellated in run-time. This can be used to make models appear smoother than they actually are.
It also is needed to make $displacementmap work.
Tip:The smoothness can be adjusted using the console variable mat_tessellationlevel <1-16>, with higher values rendering more polygons.Tip:It works only in Alien Swarm and Source Filmmaker. Confirm:Works in games other than Alien Swarm and Source Filmmaker?Warning:Studiomdl will crash if any triangles are present in the model. $subd only works with quads and n-gons with more than 3 edges. This effectively makes the SMD format unusable, meaning you have to use the DMX format, as SMD only supports triangles. The SMD format can still be used for animations, though.Syntax
$subd
Important: $subd must be stated before the $model or $body you want to apply it toExample
$modelname "example/subdivision.mdl" $cdmaterials "example/subdivision" $subd $body test "subdivison.dmx" $sequence idle "subdivision_idle.smd"
