Q3Edit

Q3Edit is an innovative, open-source level editor designed specifically for Quake III Arena, allowing users to create and modify maps directly in their web browser. This tool addresses the challenge of needing complex software installations by providing a seamless online experience. With features like a Radiant-style four-view UI, users can easily manipulate brushes, patches, and terrain while editing real .map files. The integration of id Software's q3map BSP compiler and ioquake3 running as WebAssembly enables instant compilation and playtesting of maps without leaving the tab. Ideal for both new and experienced level designers, Q3Edit ships with OpenArena assets, making it accessible for anyone looking to dive into map creation.
