Use case

Create game concept art with AI

Early in development the question is not how polished the art is, but whether the world has a point of view. Concept art lets a small team try twenty directions in an afternoon, argue about the real ones and commit. Image models are a fast way to explore silhouettes, palettes and moods before an artist, or you, invests days in final assets.

Why this approach works

  • Exploration is the point of concept art, so speed and volume matter more than perfection.
  • Describing a style once and reusing it keeps characters, environments and props looking like one world.
  • Edit models let you iterate on a chosen design, changing outfit, colour or pose without starting over.

Step-by-step workflow

  1. 1

    Write the art direction

    Summarise the world in five lines: setting, tone, shape language, palette and two reference moods. Name what the game is not, as that is often more useful.

  2. 2

    Explore with fast, wide batches

    Generate many small variations of key environments and characters. Look for silhouettes and colour relationships, not details.

  3. 3

    Lock a hero character

    Pick one design, generate a front, side and three-quarter view and write a fixed description of the outfit. Use it as the reference for every later image.

  4. 4

    Build the world around it

    Create environments, props and enemies that share the hero’s palette and shape language. Test them side by side on one sheet to catch anything that does not belong.

  5. 5

    Hand off to production

    Use the concepts as a brief for your artists, or as reference for 3D and sprite work. Keep the style sheet and prompts together so new contributors can match them.

Example prompts

Environment exploration · FLUX Schnell
Concept art of an overgrown ruined city viewed from a high balcony, towering glass buildings covered in moss and vines, hazy teal light, a small stream running through the main street, painterly style, wide composition.
Hero character turnaround · Nano Banana 2
Character design sheet of a young scavenger in a patched olive jacket, brass goggles on the forehead and a cloth satchel, shown from front, side and back views on a neutral light grey background, flat even lighting, consistent proportions.
Outfit change on a chosen design · Nano Banana 2 Edit
Keep the same character, face and proportions. Change her outfit to a heavy storm cloak in dark blue with brass buckles, add rain droplets on the fabric, keep the same pose and neutral background.

Frequently asked questions

Can I ship generated art in my game?

Check the model licence and the policy of the store you publish on, as some require disclosure of AI-generated assets. Many teams use generation for concepts and have final assets made or finished by artists.

How do I keep a character consistent?

Generate a turnaround sheet, keep a fixed written description and use an edit model with the reference image when making variations.

Is this useful for 2D sprites or 3D models?

Yes as reference. Turnaround sheets and flat-lit views are good briefs for modellers and sprite artists, though generated images are not engine-ready assets.
