GitHub - ValveResourceFormat/ValveResourceFormat: Source 2 Viewer is an all-in-one tool to browse VPK archives, view, extract, and decompile Source 2 assets, including maps, models, materials, textures, sounds, and more.
Valve's Source 2 resource file format parser, renderer, decompiler, and exporter. The library component is called ValveResourceFormat (VRF).
Contributing
This tool is based entirely on reverse engineering as Valve does not provide Source 2 documentation or code. Not all formats are fully supported. If you are interested in helping, take a look at the open issues and join our Discord. See CONTRIBUTING.md and AGENTS.md for more information.
