Set of scripts for importing Source 1 assets such as materials, models, and particle effects into Source 2. Inspired by Valve's own import utility also named source1import.

The main difference is this one is open source so you can customize it (i.e. use different shader sets).

Based off of source2utils.

• Make sure to move the entire s1 models folder to content/ before importing.
• Make sure to move the entire s1 sound folder to content/ and rename it to sounds. No import necessary.
• Make sure to have gameinfo.txt present in Import Game.
• Make sure to read this guide for importing map files.
• Materials won't be PBR ready. so you need to use some other post-conversion tool.

python materials_import.py -i "C:/.../Half-Life Alyx/game/ep2" -e hlvr  "materials/skybox"

• -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 folder. <modname> (short notation also allowed e.g. -e portal2_imported, provided the game folders sit next to eachother)
• -b <branch> Switch to a different branch. Default is hlvr. Other branches include steamvr adj sbox cs2 dota2, ordered by magnitude of support.
• [filter] Optionally a path at the end can be added as a filter.

• Python >= 3.10
• pip install -r requirements.txt
