DarkRadiant vs OpenAssetTools

DarkRadiant is a free, open-source level editor for Doom 3 and The Dark Mod, with additional listed support for The Dark Mod 2.0, Quake 4, Quake 3, and XreaL. Its workspace includes a media browser, inspectors for surfaces, patches, and lights, plus layers, grouping, and selection sets. Model and material tools include a particle editor with real-time preview, model scaling, model and skin browsers, and UV editing. It imports classic Quake and idTech map formats and exports to Doom 3, Quake 4, and Quake 3 formats. Plugins for The Dark Mod cover Stim/Response, objectives, difficulty, and conversations, alongside AI and Readable tools. A Python script interface is available, and preferences can specify fs_game for working with other Doom 3 modifications. DarkRadiant runs on Windows, Linux, and macOS, although the FAQ says macOS builds are not fully tested. The editor does not install game resources; users must point it to a supported game before editing maps.
