Primary LanguageC#MIT LicenseMIT

VRF / Valve Resource Format

GitHub Workflow Status

Valve's Source 2 resource file format parser, decompiler, and exporter. Source 2 files usually files end with _c, for example .vmdl_c.

This repository is split into three components:

  • CLI Decompiler - File data viewer, decompiler and a playground for testing new formats and features.
  • GUI Viewer - A vpk archive viewer and extractor. Also supports viewing resources such as sounds, textures, models, maps, and much more.
  • Library - Provides public API to parse resource files and some helpers.

  • Map viewer
  • Sound player
  • VPK viewer which supports opening and exporting files
  • Read only VPK API
  • Binary KeyValues3 parser
  • NTRO support

Why does VRF suck?

This tool is based entirely on a reverse engineered effort because Valve does not provide any documentation or Source 2 code (SDK or engine code), while the Source 1 SDK and leaked engine code are helpful, a lot of systems and formats have changed.

The code contained in this repository is based on countless hours of reverse engineering Source 2 games and not all intricate details have been figured out.

If you are interested in helping, take a look at the open issues.

Not all formats are 100% supported, some parameters are still unknown and not fully understood.
