Can I change the tile layout or upload a style reference?

The 4 × 4 layout stays fixed, and individual cells cannot be rearranged in the generator. You can adjust cliff height as a percentage of tile size, edge roughness and connection strength, write either region's material description, and choose a style preset, custom direction or uploaded reference image. The filled terrain region must have a material; the other region may be transparent.

Is the 16-tile base preview free to use?

The procedural base preview is free and does not require an account or credits. Submitting it for AI refinement requires login and costs 2 credits at 1K or 4 credits at 2K. Download access for the AI result follows your plan. This lets you check the corner layout and region choices before spending credits.

Can I download a single PNG tile from the atlas?

Yes. After generation, select a cell in the tile palette and download that tile as a PNG. You can also download the full atlas, a ZIP of all 16 tile PNGs, or an engine package. AI result downloads follow your plan access, and the selected task's saved layout controls the export.

How do I import a corner terrain tileset into Godot 4 or Tiled?

Export the engine package and keep its PNG beside the resource file. In Godot 4, assign tileset.tres to a TileMapLayer and use its terrain rules. In Tiled, open tileset.tsx and paint with the Corner Wang Set. Collision shapes are not included.

Will the AI tiles connect without visible seams in my map?

The AI can still introduce inconsistent texture or lighting. Import the tiles into a map with straight borders, inner corners and diagonal joins, then retouch any visible seams before shipping.

Tileset Result

Preparing tileset generation...

The filled region uses gray-white. The empty region uses blue-gray when set to Material, or a checkerboard when set to Transparent. AI adds your requested materials.

How Does This AI Tileset Generator Connect Terrain?

A fixed corner layout keeps the shape of each tile clear from preview through export.

Pixel-art 4 by 4 terrain sheet beside an assembled river landscape

This AI tileset generator starts with a fixed 4 × 4 sheet of all 16 four-corner terrain combinations. Choose a 1K atlas with 256 × 256-pixel tiles or a 2K atlas with 512 × 512-pixel tiles. The free base preview shows the filled region in gray-white; transparent gaps use a checkerboard, while material-filled gaps appear blue-gray. Adjust cliff height as a percentage of each tile, plus edge roughness and connection strength, without moving any tiles. Describe the filled terrain in your own words. For the empty region, keep transparency or choose Material and edit its text preset. Select an art-style preset, write a style direction, or upload a reference image. AI uses the fixed base to refine the textures, with the style reference supplied separately. A 1K generation costs 2 credits; 2K costs 4 credits. Inspect the result as a full atlas or as individual tiles. Download PNGs, a 16-tile ZIP, or a Godot 4 or Tiled resource package with corner terrain rules. Check the transitions in your engine before shipping; collision data and animated tiles are not included.

Where a 16-Tile Game Tileset Fits

Use one corner-based sheet to explore a terrain style and test it in a 2D map.

Top-Down RPG Floors

Describe grass, stone or dungeon flooring, then place the 16 connected tiles around paths and rooms. Review the AI texture at map scale before polishing it in a pixel editor.

Make an AI Terrain Tileset in 3 Steps

The base preview is free; AI refinement begins only when you submit a generation.

Describe Terrain and Edges

Enter the main material, choose transparency or a second material for the gaps, and adjust cliff height by percentage, edge roughness and connection strength while the base preview updates.

Two Material Descriptions

Write the terrain material as text, then leave the other region transparent or describe a second material. Presets fill the text field, so you can replace grass, water or lava with your own wording.

What Makes Sprite Flow's Tileset Generator Different?

The preview, AI input and engine files share one four-corner tile map.

One Meaning per Tile

All 16 cells have stable corner rules. The base renderer and engine exporters use the same versioned mapping, so a saved task keeps its original layout.

Choose 1K or 2K Output

New results preserve the selected 1024 × 1024 or 2048 × 2048 atlas. Each tile is 256 × 256 or 512 × 512 pixels, and the browser exports individual PNGs and ZIPs from the saved atlas.

Files You Can Inspect

A 16-tile ZIP uses row-major names starting with tile-01.png. Open or replace one cell without guessing which corner pattern it represents.

Saved Task Settings

The task records its template version, two region descriptions and style input.

Clear Generation Cost

The base preview is free; AI generation costs 2 credits at 1K or 4 credits at 2K. A failed upstream task follows the shared credit-refund workflow.

Engine Rules with Clear Limits

New exports include Godot 4 corner terrain rules or Tiled Corner Wang rules. Test texture joins yourself; collision data, animated water and 47-tile layouts are outside this workflow.
