3D Assets with AI: Clean Up and Export

AI can create or describe assets very quickly. The quality leap comes from turning that output into lightweight, named, licensed pieces that are easy to import.

  • Design asset prompts with scale, function, and constraints.
  • Clean up meshes and materials before exporting.
  • Prepare reusable assets for Godot, Unity, or web 3D.

Prompt de asset:

Crea la especificación de un asset 3D para un juego educativo.
Asset: puerta de laboratorio modular.
Estilo: low-poly limpio, ciencia ficción sobria.
Uso: se abre al recoger 3 objetos.

5. checklist de limpieza en Blender

Recommended Pipeline

  • Specify function, scale, style, camera, and constraints.
  • Generate or model a simple first version.
  • Clean up in Blender: names, origin, scale, normals, geometry, and materials.
  • Export GLB/glTF for Godot, Unity, or Three.js.
  • Verify in the engine: size, collision, lighting, performance, and warnings.
