NetRadiant-Custom vs OpenMW-CS

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.

OpenMW-CS is a free editor for making or changing mods and creating original games. Its editing tools cover files, world and mechanics data, characters, and assets, with record filters and a cell view. The editor supports plugin and script editing, mod packaging, and ESM, ESP, .omwgame, and .omwaddon formats. The project says OpenMW can run original games made with OpenMW-CS; those games do not require Morrowind. Playing Morrowind does require a legally owned copy, because OpenMW does not include its content or assets. Official releases are listed for Windows, macOS, and Linux, alongside distribution channels including Windows Chocolatey, Linux distribution repositories, and Flathub. The manual is intended as both an introduction and a reference, including for people familiar with Morrowind modding, but cautions that OpenMW-CS remains in development and the manual does not cover its shortcomings. Mods requiring MWSE, MGE XE, or MCP are incompatible because those tools modify the original Morrowind executable. The source code is released under the GNU General Public License version 3.
