When using AI to generate a Godot tileset, the goal is not to create a pretty map. The goal is to generate a tile atlas that is easy to cut, easy to import into TileSet, and predictable in a grid.
The most important goals are:
- Regular grid.
- Consistent size.
- Seamless repetition.
- No content crossing tile boundaries.
- Easy slicing in Godot.
The prompts below can be copied directly. I recommend starting with the basic ground prompt instead of asking for roads, water, walls, and decorations all at once. AI models are not always reliable with strict tile atlases. The more content you ask for, the easier it is to get misaligned cells, broken connections, or style drift.
General Purpose Prompt
This version is the most complete. It tries to generate basic ground, roads, water, walls, and decorations in one atlas.

Generate a top-down pixel art tile atlas suitable for Godot 4 TileSet.
Requirements:
- Strict top-down view
- Logical tile size: 32×32
- 6 columns × 3 rows regular grid
- Transparent background
- Every cell has exactly the same size
- No text, no labels, no UI, no characters
- Do not generate a complete map
- Keep style and lighting consistent
First row:
Normal grass, dark grass, sparse grass, dirt, sand, stone ground
Second row:
Fine grass, pebbles, flowers, fallen leaves, ground cracks, small mushrooms
Third row:
Light grass variation, dark dirt variation, wet dirt, mossy stone ground, dry sand, cobblestone ground
Technical requirements:
- All ground tiles must tile seamlessly in all four directions

Generate a top-down pixel art grass and dirt transition tileset suitable for the Godot 4 Terrain system.
Specifications:
- Logical tile size: 32×32
- Strict top-down view
- Regular grid layout
- Transparent background
- Consistent pixel density
- Consistent lighting direction
- No text, no UI, no characters, no complete scene
Required tiles:
- Pure grass center
- Pure dirt center
- Top edge where grass surrounds dirt
- Bottom edge
- Left edge
- Right edge
- Upper-left outer corner
- Upper-right outer corner
- Lower-left outer corner
- Lower-right outer corner
- Upper-left inner corner
- Upper-right inner corner
- Lower-left inner corner
- Lower-right inner corner
- Narrow horizontal dirt road
- Narrow vertical dirt road
- Cross connection
- T-shaped connection
All edge pixels must match strictly and connect seamlessly.
Do not omit inner corners or outer corners.
Each transition tile must occupy one complete grid cell.
|
This type is the easiest for AI to get wrong. You will often need to fix inner corners, outer corners, and T-junctions manually in Aseprite, Krita, or Photoshop.

Generate a top-down pixel art water tile atlas suitable for Godot 4 TileSet.
Requirements:
- Logical tile size: 32×32
- Regular grid layout
- Transparent background
- Strict top-down view
- Consistent water color and wave style
- No text, no labels, no UI, no complete map
Content:
- Water center
- Water variation tile 1
- Water variation tile 2
- Top shoreline
- Bottom shoreline
- Left shoreline
- Right shoreline
- Upper-left outer corner
- Upper-right outer corner
- Lower-left outer corner
- Lower-right outer corner
- Upper-left inner corner
- Upper-right inner corner
- Lower-left inner corner
- Lower-right inner corner
- Small water ripple
- Floating leaf
- Stone in water
Use natural dirt and a small amount of grass for shorelines.
All edges must connect seamlessly in all four directions.
No tile content may cross its own grid cell boundary.
|
For water assets, check two things carefully:
- Whether the water center tiles seamlessly.
- Whether shorelines and inner/outer corners really connect.

Generate a top-down pixel art dungeon tile atlas suitable for Godot 4.
Specifications:
- Logical tile size: 32×32
- 6 columns × 5 rows regular grid
- Transparent background
- Strict top-down view
- Dark gray stone dungeon style
- Consistent pixel density and lighting direction
- No characters, no complete room, no UI, no text
Content:
- Normal stone floor
- Cracked stone floor
- Mossy stone floor
- Blood-stained stone floor
- Stone wall center
- Stone wall top
- Stone wall left and right edges
- Wall inner corner
- Wall outer corner
- Door opening
- Iron door
- Stone pillar
- Torch base
- Wooden crate
- Wooden barrel
- Rubble
- Bones
- Chains
- Floor trap
All floor tiles must tile seamlessly.
Wall edges and corners must connect correctly.
Every object must stay completely inside its own grid cell.
|
Dungeon assets often fail in one of two ways: walls become side-view objects, or the whole image becomes a complete room. Keep emphasizing “top-down view”, “no complete room”, and “only a tile asset sheet”.

Generate a top-down hand-drawn cartoon style tile atlas suitable for Godot 4 TileSet.
Requirements:
- Logical tile size: 64×64
- Strict top-down view
- Soft hand-drawn style
- Clear outlines
- Consistent brush strokes
- Consistent lighting
- Regular grid layout
- Transparent background
- Do not generate a complete map scene
- No text, no UI, no characters
Content:
Grass, dirt, sand, stone path, water, road edges, grass-to-dirt transition edges, small flowers, small stones, grass bushes.
All base ground tiles must tile seamlessly.
Edge patterns must connect with neighboring tiles.
Each tile must remain independent and must not cross into another cell.
|
Hand-drawn style is more likely to produce uneven edges than pixel art. After generation, realign the grid in an image editor before importing into Godot.

Practical Generation Settings
Start with these settings:
1
2
3
4
5
|
Logical tile size: 32×32
Atlas layout: 6×4 or 6×5
Final generated image: 1024×1024 or higher
Background: transparent
Style: pixel art
|
One important note: AI models usually will not output a truly strict 32×32 cell grid.
“32×32” mainly tells the model the design proportion. After generation, you still need to use an image editor to:
- Crop the canvas.
- Create a regular grid.
- Realign each tile.
- Scale tiles to true
32×32.
- Fix the edges.
- Export PNG.
For smoother automatic slicing in Godot TileSet, the final atlas should ensure:
- Canvas size is divisible by tile size.
- Every tile sits inside a fixed grid cell.
- No outer border.
- No irregular spacing.
- No content crosses cell boundaries.
The Most Reliable Batch Workflow
Do not generate a full large atlas in one pass. Use this order:
- First image: base ground.
- Second image: road connections.
- Third image: water and shorelines.
- Fourth image: walls and cliffs.
- Fifth image: flowers, grass, and pebble decorations.
For the second batch and later, add this to the prompt:
1
2
|
Keep exactly the same colors, brush strokes, pixel density,
view angle, lighting direction, and outline style as the previous asset set.
|
Even then, different batches may drift in style. For a real project, final color grading and cleanup are usually necessary.

Generate a top-down pixel art base ground tile atlas suitable for Godot 4 TileSet.
Logical tile size: 32×32.
Atlas uses a 6 columns × 3 rows regular grid.
Transparent background.
Strict top-down view, no perspective, no isometric angle.
All tiles have exactly the same size and are neatly aligned.
Consistent pixel density, color style, and lighting direction.
First row:
Normal grass, dark grass, light grass, normal dirt, dark dirt, sand.
Second row:
Gray stone ground, mossy stone ground, cobblestone ground, wet dirt, dry grass, gravel ground.
Third row:
Small flower decoration, grass bush decoration, small stone decoration, fallen leaf decoration,
ground crack decoration, small mushroom decoration.
All base ground tiles must tile seamlessly in all four directions.
Decorations must stay completely inside their own tile.
Do not generate a complete map.
No characters.
No text, numbers, labels, UI, borders, or preview notes.
Do not let any pattern cross into neighboring tiles.
Output as a single transparent PNG atlas.
|
This is the best first test asset. If Godot can slice it with a regular grid and the base ground tiles can repeat, it is already good enough. Add roads, water, walls, and decorations later instead of trying to make a complete atlas on the first attempt.
