Source 2 Viewer

Summary

Source 2 Viewer is a free, open-source tool for exploring and working with Source 2 game assets. It browses VPK archives, where users can search, extract, and create archives, including all VPK versions and Source 1. Its viewer handles maps, models, materials, textures, sounds, physics, animations, particles, shaders, and other resource types. The 3D renderer displays supported assets from CS2, Dota 2, Deadlock, and other Source 2 games, with real-time lighting and animation playback. Maps, models, physics, and animations can be exported to glTF 2.0, with material conversion and batch export. Maps, models, and materials can also be decompiled into editable formats for Hammer, ModelDoc, and Source 2 Workshop Tools. Texture tools cover channels, depth layers, mip levels, cubemaps, and HDR, with image export. The audio player supports WAV, MP3, and Source 2 formats. The graphical interface is Windows-only, though the guide describes running it on Linux and macOS through Wine; the command-line version is available on all three. Some export data may be lost, and not all formats are fully supported.

Who it is for

It suits users exploring or exporting assets from Source 2 games, including people working with compatible 3D tools. The command-line utility supports Windows, Linux, and macOS; the graphical interface is aimed at Windows users.
