Tiled Wang Set Export — Terrain Sets from an Autotile Sheet
Filling in a Tiled Wang set tile by tile is the same chore as Godot peering bits. The Studio writes the Wang set from the recognised layout — mixed, edge or corner, one colour per terrain — and adds a sample map drawn with the Tiled rule.

What it does
- .tsx with the Wang set type that fits the layout (mixed for blob, edge for 16-side, corner for 16-corner / dual grid).
- sample.tmx: a map drawn with the Tiled rule; corner sets as a layer offset by half a tile.
- Checked with Tiled 1.12.2's own --export-tileset / --export-map readers and tmxrasterizer (pixel-exact).
- The terrain brush itself was not driven (Tiled scripting does not run headless on Windows).
How to do it
- Drop the tileset and apply its layout.
- Paint a test map with the Tiled rule to preview.
- Export the Tiled bundle.
- Open the .tsx or sample.tmx in Tiled.
Engine exports and how each was checked
"Verified" means the exported files were loaded by the real engine or tool on real CC0 assets and the result was compared with the source. Anything that was not loaded is labelled as such.
| Target | Files | Check |
|---|---|---|
| Godot 4 TileSet | PNG · nerulio-tileset.json · nerulio_tileset_import.gd | Verified Godot 4.7.2The included import script builds the TileSet with terrain peering bits; a map painted with set_cells_terrain_connect equals the Studio preview in every cell on 9 corpus sheets. |
| Tiled | .tsx Wang set · sample.tmx | Verified Tiled 1.12.2Tiled's own readers load every Wang ID as written and the sample map renders pixel-exact. The terrain brush itself was not driven. |
| Unity 6 Rule Tile | nerulio-ruletile.json · Editor/NerulioRuleTileImporter.cs | Verified Unity 6000.5.3f1 + 2D Tilemap Extras 8.0.3Blob and side sets: a painted Tilemap shows the predicted sprite in every cell. Corner / dual-grid sets are not exported to Unity. |
| LDtk | .ldtk (1.5.3) · rules · sample level | Partly verified LDtk 1.5.3 schema + loaderAccepted by the LDtk JSON schema and its official loader, and the rules re-run to the exported tiles; not opened in the LDtk app. |
Evidence
Layouts identified from the pixels alone on the tile corpus: 4 blob-47 templates and 2 Wang templates with high confidence, a real 64 px cave tileset with medium confidence — every tile's bits right. Godot 4.7.2 painted every test cell exactly as the Studio predicted (485/485 per blob set, 251/251 on a 4-terrain dual-grid pack); Tiled 1.12.2 read every Wang ID back; Unity 6000.5 matched on every painted cell of the blob and side sets.
Limits
- Tiled's terrain brush, the LDtk app and Godot's editor painter were not driven; the checks use the engines' readers and set_cells_terrain_connect.
- Unity gets blob and side sets only; several terrains become several Rule Tiles with no transitions between them.
- Isometric and hex tiles, animated tiles, occlusion and navigation layers are out of scope.
- Suggesting bits without a known layout needs a reference "full" tile; on side-only path templates the guess can fail until you select it.
Questions
Why is the lone "island" tile missing from my Wang set?
Tiled drops a Wang tile whose ID is all zeros, so a one-colour blob set's isolated tile is not written; the Studio's Tiled rule marks such lone cells.
Can Phaser load the sample map?
The .tmx is a Tiled map; Phaser reads Tiled JSON with embedded tilesets, which you can export from Tiled.
Is it free, and do I need an account?
Everything on these pages is free and works without an account. There is no watermark and no export that is held back.
Are my sprites uploaded?
No. The Studio decodes, packs and exports in this browser tab. Projects are autosaved in the browser (IndexedDB) and can be saved as a .nerulio file.
Does it need Aseprite or an engine plugin installed?
No. .aseprite files are read and written in the browser, and each engine bundle carries what that engine needs (for Godot, the import settings and scene; for Unity and the Godot TileSet, a small editor script).
