Art
The game's art was created for the game. Part of it was produced with the help of generative tools and then edited and approved by the developer:
- 2D illustrations and interface art: original vector art, and images generated with OpenAI's image generation tool (output rights assigned to the user under OpenAI's terms).
- Several 3D props and characters: generated with Meshy on a paid plan and optimised in Blender. Under Meshy's terms, assets created on a paid plan belong to their creator, may be used commercially and need no attribution.
- Doors, desks and other props: procedural geometry made in Blender without generative AI.
