Steps
Once connected (see setup above), use the Game Art Generator tool:
- Describe each city or region and how it should differ visually — architecture style, palette, density.
- Generate a miniature render for each using miniature_city.
- Ask ChatGPT to compare the renders and confirm each city feels visually distinct while still belonging to the same world.
- Package the approved renders with brief descriptive notes for the world map and lore document.
Example Prompt
Try this with ChatGPT using the Game Art Generator tool
Use game-art-generator to create miniature city renders for three factions in my strategy game: a forest elven city in the trees, a dwarven mountain fortress carved into a cliff, and a human port city on a bay. Compare them — do they feel like different cultures in one coherent fantasy world?
Tips
- Define what visual language ties the cities together — shared palette warmth, similar miniature scale — before making them distinct.
- Ask ChatGPT to flag if any city render looks generic rather than faction-specific.
- Use the comparative output to write the world's visual lore — what makes each civilization look the way it does.
