OpenApe: reconstructing the Call of Duty 4 Asset Manager

OpenApe reimplements the Call of Duty 4 mod tools' asset_manager.exe as a C++20 desktop editor. The author attributes its format knowledge to machine-assisted analysis of decompiled binaries. It reads GDF definitions and GDT game data, and previews models, animations and materials using the game's compiled shaders.
