$modelname
The $modelname QC command must be used. It specifies the output folder (relative to game_dir/models/
) and filename of the compiled model.

Example
$modelname "weapons/shell.mdl" $cdmaterials "models/weapons/" $body shell "shell-ref.smd" $sequence idle "shell-idle.smd"
Including .mdl
is optional but makes the script easier to understand.
