A block texture is repeated hundreds of times on a wall, a floor or a hill. If the edges do not match, every join shows as a line. Blocks are the hardest textures to get right with a normal AI image tool, because those tools draw a picture with a frame, a focal point and lighting that changes across the image.

The block generator asks the model for a flat, top-down surface that fills the square, then blends the picture with a shifted copy of itself so that the edges continue into each other. After that it shrinks the result to the exact pixel size and reduces the palette, so it looks like a game block and not like a photograph of a wall.

Check the tiling before you download

Each block result shows a 3 by 3 tile preview and an isometric cube. If you see a grid of lines or a spot that repeats too clearly, roll another version with More like this. You can also turn tiling off for a single, non-repeating picture.

Prompts that tile well

Describe a surface, not an object. Mention the material, a pattern or a small feature, and avoid one large item in the middle.

Mossy cobblestone with cracks and small purple crystals.
Dark oak planks with iron nails and scratches.
Glowing lava stone with thin orange veins.
Frozen ice bricks with blue frost.

Resolutions and palettes

At 16x16 a block uses about 12 colors and tiles easily. At 32x32 there is room for cracks and patterns, with about 22 colors, and seams are easier to see, so test the tile. A 64x64 size is available with a credit pack.

Top, side and bottom faces

Some vanilla blocks use different pictures per face, such as grass blocks and logs. Generate each face as its own texture and name them after the vanilla files, for example grass_block_top and grass_block_side, then export them together.

Questions

How does the seamless tiling work?⌄

The picture is blended with a copy of itself shifted by half a tile, with the strongest blend at the edges, then reduced to real pixels. The edges end up continuing into each other.

Can it make animated blocks?⌄

Not yet. Results are static single frames. Animated textures like water and lava need a tall strip of frames and an extra mcmeta file, which you can build from several generated frames.

Which sizes are free?⌄

16x16 and 32x32 work with the free credits. 64x64 needs a credit pack.
