1. When your model is ready, set up everything you want as a separate SMD/DMX in its own collection.

2. Click on Find Engine Path in the QC Generator section of the Properties Editor's Scene tab.

Note: This button will only work seamlessly if your blend file is in a folder like <root>/content/<game>/<whatever>, where <root> is some arbitrary folder, <game> is the name of your game (e.g. hl2) and there exists a source engine game folder (the one that would contain GameInfo.txt) in <root>/game/<game> and a bin folder with studiomdl.exe in <root>/game/bin.

This will set the following options for Source Engine Export and QC Generator:

Option	Path
Your .blend File	<root folder>\content\hl2mod\models\props_generic\television03\television03.blend
Engine Path	<root folder>\game\bin
Game Path	<root folder>\game\hl2mod
MDL Name	props_generic\television03.mdl
CD Materials	models\props_generic

3. Set up your SMD/DMX models with Blender Source tools an export them all.

4. Set the parameters of your QC to generate, you can choose a model to be your collision model if desired, and then click Write QC

5. If you have Open in Text Editor checked then the generated QC file will open in a Blender text editor. If there is no Blender text editor on your screen, the largest area (usually the 3D view) will be changed to a text editor.

6. If you have Automatically Overwrite File checked then the QC file will be saved for you automatically.

7. You can then simply click on the QC file under the Source Engine QC Compiles section.

8. Congratulations, you've just fully compiled a MDL file! Open HLMV to see how it looks.
