How to Use

Drop a single square texture into the center tile field (the middle square of the 3×3 grid).
Tilez will automatically generate a complete 47-blob tilemap ready for use in video games.

The editor provides a live preview of your tile in a 3×3 arrangement.

Controls:

• Drag edges of the ring to adjust thickness
