Export & Formats
Your terrain, your way. Save it, share it, deploy it.
Export Formats
| Format | Extension | Use Case |
|---|---|---|
| BBT Bundle | .bbt |
Full terrain package — heightmap, textures, water config, generation parameters. Re-import into Terraformer for continued editing. |
| GLB Mesh | .glb |
Standard 3D mesh format. Import into Blender, Unity, Unreal, Three.js, or any 3D pipeline. |
| Heightmap | .png |
Raw height data as a grayscale image. Use in any terrain engine that accepts heightmaps. |
| World Export | NEXUS message | Push terrain directly to poqpoq World via the NEXUS postMessage bridge. World Mode only. |
BBT Bundle Format
The BBT (BlackBox Terrain) format is a ZIP archive containing everything needed to fully reconstruct the terrain:
- heightmap.png — 16-bit grayscale heightmap
- textures/ — all biome texture images
- terrain.json — generation parameters, water config, museum block settings
- metadata.json — export timestamp, version, author
BBT files can be re-imported into Terraformer at any time. This is your "project save" format.
Save a BBT before making destructive edits. It's your undo insurance. BBT files are typically 2–10 MB depending on texture resolution.
GLB Export
The GLB export produces a standard glTF binary file containing the terrain mesh with embedded textures. This is the universal format for getting your terrain into other tools:
- Blender —
File → Import → glTF 2.0 - Unity — drag into project assets
- Unreal — import as static mesh
- Three.js / Babylon.js — load with the standard GLTF loader
Export to World
When running in World Mode (launched from poqpoq World), the Export to World hero button sends terrain data to the parent World app via the NEXUS postMessage bridge. No file downloads, no manual uploads — one click and the terrain appears in your world.
See poqpoq World Integration for the full workflow.
