NetRadiant vs Remere's Map Editor

NetRadiant is a free, open-source 3D game level editor that uses brushes to build levels. It has first-class compatibility with Xonotic and Unvanquished and supports about 30 other games, with support varying by game. The project is driven by Xonotic, receives support from Unvanquished, and is maintained by a community of gamers, mappers, modders and game developers. It originated as a fork of Id Software’s GtkRadiant project. Listed downloads include Linux 64-bit, Windows 32-bit and 64-bit, macOS 64-bit and FreeBSD 64-bit builds. The builds include daemonmap for Unvanquished navmesh generation and q3map2 patches for Smokin’ Guns. Released Xonotic files work without an extra mapping support package. Linux use requires a working GTK2 and OpenGL environment. Windows builds offer optional Mesa3D rendering, described as a workaround for some older Intel chips on Windows 10. A 2022 project post described macOS support as new and potentially rough, including possible multi-screen configuration problems. The download page lists version 1.5.0-20220628.

Remere's Map Editor is a free map editor for OpenTibia, an open-source implementation of the MMORPG Tibia. It provides tools for creating and managing maps, including tile and entity placement, terrain flood fill, waypoint tools, and animation previews. Search tools can locate items and find unique IDs, action IDs, containers, and writable items in a selected area. Users can import and export zones and export a minimap for a selected area. Version 4.0 adds compatibility with the Canary and Assets Clients repositories, reads assets from client 11 or higher, and includes Lua scripting and a real-time monitor for FPS, CPU, and RAM. The project supports Windows, Linux, and macOS and provides compilation guidance for each; compiling requires wxWidgets 3.0 or later and Boost 1.55.0 or later. The project is licensed under GPLv2. Its README points to the official website for releases and provides a separate download link for version 3.X until it is added to that site. The free plan costs nothing; redistribution is allowed only in unmodified form.
