Bract Editor
Edit the world you ship.
A world editor that runs in the browser on the same WebGPU renderer as the engine. No export step and no preview approximation: what you see while building is what players see.

In the box
Every tool a world builder needs.
The editor is built on the engine's own modules, so each tool works on real engine data instead of a copy of it.
Modeling with CSG
Edit topology, select faces and regions, deform meshes and run boolean operations, all with undo and revision history.
Materials
A material library, palette inspector and surface presets, previewed live in the engine renderer.
Lighting
A lighting library and per-light inspector, rendered with the same lighting the game uses.
Terrain and biomes
Shape generated terrain and edit biome layers, then watch the world rebuild.
Scatter and trees
Tree generator controls and biome-aware scatter placement for foliage at world scale.
Scene and entities
Scene tree, entity inspector, picking and transform gizmos.
Frame stepping
Pause, step and scrub simulation frames to debug animation, physics and effects precisely.
