NetRadiant vs Sprite Fusion

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.

Sprite Fusion is a tilemap editor for designing 2D game maps, available in a browser and as a desktop app. You can import tilesets by dragging and dropping, loading an image, or pasting one from the clipboard, then draw with pencil, fill, selection, and attributes tools. Autotile layers use neighboring cells to resolve tiles, with variants, weights, and reusable rule presets. Collision layers can be exported for supported targets. Game engine exports include Unity, Godot 3 and 4, Defold, Bevy, Love2D, GDevelop, Phaser, Cocos, and GB Studio; other formats include TMX, Sprite Fusion JSON, PNG, and UVTT. UVTT exports can represent collider layers as walls for virtual tabletop software such as Foundry VTT. The Web Edition costs nothing and limits map exports to 4.5MB. The Desktop Edition costs $14.99, paid once, works offline, and exports maps of any size. It has Windows and macOS builds, plus an experimental 64-bit Linux build.
