obj2mdl

Converts a .obj file to a source .mdl. It will create intermediary .smd files, for studiomdl.exe to use.

Usage

Run the file and follow the directions, or use the command line:

• obj2mdl.py model.json

Run obj2mdl.py -help for more information.

Configuration

Program

The config.json file should look like this:

{
  "engine_path": "PATH_TO_BIN_FOLDER",
  "game_path": "PATH_TO_GAME_FOLDER"
}

• engine_path is the folder that contains studiomdl.exe.
• game_path is the folder of the game, for example something like: C:\Program Files (x86)\Steam\SteamApps\common\Half-Life 2\hl2.

Model Config

To get the auto-generated collision model, simply set obj_collision_model to the value of obj, and make sure qc -> collisionmodel -> concave is false. If material -> use_file is true, then the materials specified in the OBJ file will be used. Otherwise, every face will recieve the material name given by material -> name.

The contents of MODEL_NAME.json should look like this:

{
  
  "name": "sofa",
  
  "obj": "sofa.obj",
  "obj_collision_model": "sofa_collision.obj",

  "material": {
    "use_file": false,
    "name": "sofa"
  },
  
  "qc": {
    "surfaceprop": "wood",
  }
  
}

All attributes of qc correspond to the output of the qc. If a property isn't specified, a set default is used. Alternatively, you can provide your own QC file:

{
  
  "name": "sofa",
  
  "obj": "sofa.obj",
  "obj_collision_model": "sofa_collision.obj",

  "material": {
    "use_file": false,
    "name": "sofa"
  },
  
  "qc": "sofa.qc"
  
}
