Source 2 Viewer vs TTGames Explorer Rebirth

Source 2 Viewer is a free, open-source tool for browsing VPK archives and inspecting or exporting assets from Source 2 games. It can search, extract, and create archives, including VPK versions from Source 1. Its renderer displays maps, models, physics, and particles with real-time lighting and animation playback. The tool also inspects textures, audio, shaders, and other Source 2 resources. Maps, models, physics, and animations can be exported to glTF 2.0, with material conversion and batch export; maps, models, and materials can 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. Its 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 utility is available for Windows, Linux, and macOS. The GUI is portable and requires no installation. Some data may be lost during export, and reverse-engineered format support is incomplete. The project is volunteer-built and says it is not affiliated with Valve.

TTGames Explorer Rebirth is a free, open-source utility for exploring and extracting assets from TTGames LEGO video games. It browses and extracts .dat, .fpk, .pac, and .pak archives, with batch extraction for multiple assets. Supported text files such as .txt, .xml, and .csv open in a color-coded viewer. The tool can preview textures including .dds and .tex and export them as PNG. Audio formats including .adp, .cbx, .mp3, and .ogg can be played and converted. It also handles .ft2 fonts, .tsh texture sets, shaders, and models, with previews for shaders and models. TTGames compression and encryption methods include LZ2K, Deflate, and RC4; Deflate support excludes .an4 files. The project is distributed under the MIT License.
