QC Editing

                While an MDL file may have been used by MANY programs from the 90's and early 2000's, The focus here is Valve's MDL format for Gold-source. An MDL file Consists of 3 files:

".QC" (Q.uake C) A script file that compiles SMD files, assigns animation SMD's and locates textures.

static (non-animated) QC template

$modelname Cube.mdl
$cd "./"
$scale 1
$cliptotextures
// reference mesh
$body studio cube
// Animation
$sequence "static" "cube"

more on QC scripting

".SMD" (S.tudio M.DL D.ata) A three dimensional model file used by the Source and Gold-source engine, it is stored in an ASCII text format, However it should be noted that technically there are 2 SMD types: Model data and animation data

Example SMD (src file name: Cube.smd*)
