Pixel Art Tileset Generator (16x16, 47-tile blob autotile)

Pick a theme and a seed. The tiles are generated procedurally by code, written with AI assistance, and the same theme and seed always give the same pixels.

Theme, seed and size

Generated sheets

Autotile sheet: 12 columns by 4 rows of 16x16 tiles (192x64 pixels), 47 tiles used. Extras sheet: 4 ground variations, 4 secondary-terrain variations and 8 decor props (128x32 pixels). The download is one PNG with the autotile sheet on top and the extras sheet below it.

How to use it

What is a 47-tile blob sheet?

A blob autotile looks at the 8 neighbours of a cell (N, NE, E, SE, S, SW, W, NW). Corner neighbours only matter when both touching edge neighbours are filled, which leaves 47 distinct tile shapes out of 256 possible neighbour masks. The sheet holds one tile for each shape, so a map painter can pick the right edge, corner or inner corner automatically. The mask for every tile is listed in the bitmask table.

How the seed works

The seed is a number. If you type digits (0 to 4294967295) that number is used as is. Any other text, such as a project name, is turned into a number with a fixed hash, so the same text always gives the same seed. An empty field uses seed 1. The seed changes the texture of the ground, the rim noise and the decor props; the layout of the 47 tiles never changes.

Import into Godot 4

Copy the PNG into your project. In the import dock for the file, choose Texture and turn the Filter off for crisp pixels (or set the project default texture filter to Nearest). Create a TileSet, set the tile size to 16x16 and add the PNG as an atlas source. If you exported at 2x use 32x32, at 4x use 64x64. Then paint the terrain using the layout in the bitmask table.

Import into Tiled

Choose New Tileset, based on a Tileset Image, and pick the PNG. Set tile width and height to 16 (32 for 2x, 64 for 4x), margin 0 and spacing 0. The autotile sheet is 12 columns by 4 rows, so Tiled shows 48 cells; the last one is intentionally empty.
