rQuake Editor

A standalone BSP map editor for Quake, built on top of the rQuake engine.

Overview

rQuake Editor loads and renders Quake BSP maps using the original engine's model loader and OpenGL renderer, with a Dear ImGui interface layered on top for editing. It reuses a minimal subset of the engine (model loading, math, memory, drawing) while stubbing out everything else (networking, sound, input, server).

Building

Requires CMake 3.16+, a C99/C++11 compiler, SDL2, and OpenGL.

git clone --recursive https://github.com/retcode/rQuake-Editor.git
cd rQuake-Editor
cmake -B build
cmake --build build

On Windows, SDL2 is expected via vcpkg at C:/vcpkg/installed/x64-windows. On macOS/Linux, install SDL2 via your package manager.

Running

Copy PAK0.PAK and PAK1.PAK from a Quake installation into build/id1/ (or build/Debug/id1/ on Windows), then run:

./build/rqedit              # macOS/Linux
build\Debug\rqedit.exe      # Windows

Pass a map path as an argument, or it defaults to maps/e1m1.bsp.
