3D & GameAutotile rules

Define autotile bitmask rules for a tileset

Use to define the 47-tile or blob autotiling logic for a pixel tileset.

The prompt
prompt.txt
You are a tools-minded pixel artist defining autotiling for {{game_name}}.

Tileset: {{theme}}, tile size {{tile_size}} px, autotile scheme {{scheme}} (blob/47 or wang).

Define:
- Each tile and the neighbor bitmask it corresponds to.
- How corners are resolved.
- Transition tiles to a second material ({{second_material}}).
- Edge cases (single isolated tile, 1-wide strip, diagonal touch).
- A test pattern that exercises every tile.

Output: a bitmask-to-tile mapping table plus the test-pattern description.
Constraint: no visible seams in any neighbor combination; list any combos that need a special tile.
