  • The compile tools need a QC file containing model information
  • Unlike a regular brush, any $surfaceprop set in the prop's material (.VMT) files is ignored; instead, it is set here in the .QC file.

  • texture must also be compiled into a VTF file just like any normal texture. However, it must include the $model declaration. This was the VMT file used for pcgmag.tga: 

     

    "VertexLitGeneric" { 	"$baseTexture" "models/pcgmag" 	"$model" 1 }
  • if it was UV-mapped using pcgmag.tga, the model will use the material pcgmag.vmt. You can use multiple texture files on the same model.
  • UV map the model in Blender will be used as the name of the material file for the model.
  • $texturegroup skinfamilies {  { "pcgmag" }  { "pcgmag_cover2" } }
  • Adding collisions
  • Complex collision models
  • But to make it a non-convex object, such as a table, we have to be more careful if we want the prop to collide with things as we would expect.
  • each leg is a tapered cuboid

  • As before, we need a table_idle.smd file to define the idle animation, which can be identical to the pcgmag_idle.smd file we used above. 

    Now we need a .qc file for the table prop: 

     

    $modelname rof/table.mdl $cdmaterials "models/rof" $scale 12.0 $body studio "table.smd" $sequence idle "table_idle" fps 1 $staticprop $surfaceprop "Wood_Furniture"  $collisionmodel "table_phys.smd" {    $automass    $concave }  $keyvalues {    "prop_data"    {        "base"  "Wooden.Large"    } } 

     

    Note the differences from before. We've upped the scale a little, and set the $surfaceprop to "Wood_Furniture" and the prop data to "Wooden.Large" to reflect the type of prop we're making. In the $collisionmodel section, instead of the $mass command, we've used $automass. This makes the model compiler compute a mass for the object based on its size and material type. We could instead have explicitly specified the object's mass with the $mass command as before.  

    We've also added the $concave command to that section. This makes the compiler build a non-convex collision mesh for each part of the table_phys.smd file, rather than lump them all together in one convex shape. We can tell if this has worked when compiling the .qc file.
  • $concave command
  • check the collision model by using the model viewer (hlmv.exe). On the "physics" tab, click the Highlight button and the collison mesh shows as a red wireframe. If we've got it right, it should look like the picture on the left: the wireframe follows each part individually. If we've got it wrong, it might look the picture on the right: the wireframe is a single shape wrapping the whole object.
