NetRadiant-Custom vs Reloaded-II

NetRadiant-Custom is a free, open-source level editor for games based on id Tech, available on Windows, macOS and Linux. Its primary focus is Quake, Quake 3 and Quake Live, while releases include configurations for additional games. Users can create and manipulate brushes and entities in the 3D view, with geometry tools for vertex editing, face extrusion, patch thickening and CSG shell modification. Texture tools support UV alignment, drag painting, copying textures between brush faces and patches, and locking textures during vertex or edge edits. Keyboard shortcuts, interface themes and fonts are customizable. Viewports offer anisotropic texture filtering and optional MSAA. When region mode is enabled, working compilations build only the map section in that region. Bundled Q3Map2 tools include automatic map packaging and BSP import and export as JSON; its Assimp library supports more than 40 model formats. Supported formats include .map, .bsp, .pk3, .dpk, .dpkdir, Valve 220, brush primitives, axial projection, .def, .ent and .fgd. Ready-to-use packages are available in the project's Releases section.

Reloaded-II is a free, modular framework for creating mods for x86 and x64 games. Mods can be written in .NET and C#, and native mods are also supported; the project says they can use libraries and NuGet packages while running in isolation. The loader includes dependency ordering, early hooks, hot reload, real-time console and file logging, and Visual Studio debugging and profiling support. Its launcher manages multiple games and per-game mod sets, with built-in configuration, automatic updates and a mod downloader that offers one-click downloads on supported websites. The automatic installer installs Reloaded-II and runtimes in one click; the documentation says this usually takes under 30 seconds. The project says it does not modify game files and can be removed by deleting its folder. Windows users are directed to the installer, while Linux users are directed to a setup guide. Listed platforms include Windows, Linux via Wine or Proton, and macOS via Wine. The FAQ advises against using Reloaded-II with multiplayer games because games with effective anti-cheat may ban users.
