What Autotile Builder does

A terrain that joins on every side needs 47 tiles, and drawing them all by hand is the slow part of any tileset. The Autotile Builder takes a small template, a plain 3x3 island is enough, and builds the whole set: 47 tiles for blob autotiling, or 16 for sides and corners.

A seam check paints a random map from your tiles and names the piece to fix when two tiles do not meet. It also writes the engine files: a Godot 4 TileSet with terrain peering bits, a Tiled wang set with animations, and RPG Maker-compatible A1 and A2 sheets. A terrain can animate over 2 or 3 frames, as for water.

How it works

  1. Load a 3x3 island or a 2x3 template, or start from a sample.
  2. Check the full set and the seam check on a random map.
  3. Add frames for animation or more terrains.
  4. Save the atlas with its JSON, or the file for your engine.
