$subd

An example of a low-poly sphere.

Same model, utilizing $subd and mat_tessellationlevel 16.

The QC command $subd 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.

Tip:The smoothness can be adjusted using the console variable mat_tessellationlevel <1-16>, with higher values rendering more polygons.

Confirm:Only works with 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.
