Import Source game content into Source 2

source1import

Set of scripts for importing Source 1 assets such as materials, models, and particle effects into Source 2. Inspired by Valve's own source1import.exe (written in C++ and Perl), this one is in Python.

Requires:

Python 3.9
python -m pip install -r requirements.txt

Installing:

Download as ZIP and Extract
Open folder, press Ctrl + L, enter cmd and run the following commands

python -m pip install -r requirements.txt
cd utils

All set. Use python materials_import.py --help or read below examples to get started.

Usage

Scripts are launched via command line:

-i <dir> This should be an absolute path pointing into a source1 game directory containing gameinfo.txt

-e <dir/modname> Path to source2 mod/addon. <modname> (e.g. -e portal2_imported) instead of an absolute path will only work if the input folder -i is placed inside a source2 /game/ environment which also contains <modname>.

Usage examples:

cd utils
python scripts_import.py   -i "C:/.../Team Fortress 2/tf" -e "D:/Games/steamapps/common/sbox/addons/tf_source2"
python particles_import.py -i "C:/.../Portal 2/portal2" -e "C:/.../Half-Life Alyx/game/hlvr_addons/portal2"
python scenes_import.py    -i "C:/.../Half-Life Alyx/game/lostcoast" -e hlvr_addons/lostcoast_source2
python panorama_import.py  -i "C:/.../Half-Life Alyx/game/csgo" -e csgo_imported
python models_import.py    -i "C:/.../Half-Life Alyx/game/l4d2" -e l4d2_source2
python materials_import.py -i "C:/.../Half-Life Alyx/game/ep2" -e hlvr

Note:

• Make sure to import texture content first (.vtf files), via VTFEdit :: Tools -> Convert folder, or the included vtf_to_tga.py, using the same parameters.

  Materials and particles won't convert correctly if .tga files aren't present inside /content/<modname>/materials/
