QC

For a list of QC commands, see Category:QC Commands.

To learn how to compile a model, see Compiling a model.

A QC file is a script which controls the process of "compiling" SMDs into a binary model that can be loaded into a game. A QC configures the model's location and name, while SMD files are used to provide geometry, collision meshes and animations, how the model reacts when shot, and so on.

Comments can be ends of lines starting with //, or blocks contained between /* and */. Source additionally supports end of line comments starting with # or ;.

Paths usually can contain a combination of either forward or backslashes, except for , which requires forward slashes due to adding support for  escape sequences in QC files (due to shared code between VBSP and StudioMDL).

Note:Although the "QC" file extension is derived from the QuakeC programming language used by Quake, the syntax of StudioMDL QC files is significantly modified from the  C-like syntax used by QuakeC.

Tip:Shared QC files intended for use with $include are typically given the extension qci, and outdated or deprecated QC files are typically given the extension qcx. This prevents them from attempting to be compiled when batch-compiling an entire folder.

Simple example

Here is a very simple Source QC file for a solid model without any animation or special properties (click on each command for details):

$modelname	"props_sdk/myfirstmodel.mdl"
$body mybody	"myfirstmodel-ref"

$surfaceprop	combine_metal
$cdmaterials	"models/props_sdk"

$sequence idle	"myfirstmodel-ref" // no animation wanted, so re-using the reference mesh

$collisionmodel	"myfirstmodel-phys" { $concave } // can be omitted if no collision is needed

Likewise, for GoldSrc:

$modelname	"myfirstmodel.mdl" 
$cd		"." // look for SMDs in the same directory as the QC
$cdtexture	"." // look for BMPs in the same directory as the QC
$body mybody	"myfirstmodel-ref"
$sequence idle	"myfirstmodel-ref" // no animation wanted, so re-using the reference mesh

Note:The .smd file extension should usually be omitted from mesh and animation file names. Including it will cause StudioMDL to fail to load the file.

StudioMDL automatically looks for files in this order when no extension is present:

VRM, SMD, SMA (SMD), PHYS (SMD), VTA, OBJ, DMX, XML (DMX)

FBX, VRM, DMX, MPP (DMX), SMD, SMA (SMD), PHYS (SMD), VTA, OBJ, XML (DMX), FBX
