A significant portion of AI-generated assets (around 20% in this case) will require revision. The core advantage is not a perfect initial hit rate, but the extremely low cost and speed of iteration—regenerating or tweaking assets is an order of magnitude faster than traditional 3D modeling revisions.
Successful AI asset generation relies on a pre-defined art direction document, or "bible," translated into a locked prompt template. The AI tool's role is to execute this pre-established direction to ensure a consistent visual style, not to invent the style itself.
Generative AI doesn't eliminate the need for artists; it transforms their work. Time previously spent on the manual labor of modeling is reallocated to higher-value tasks like defining the world's visual needs, directing pacing, and ensuring assets contribute meaningfully to the game.
AI tools generate assets in isolation, causing inconsistent scaling when imported into an engine like Roblox. Each object must be manually resized against a player character. Furthermore, default collision meshes for complex geometry like archways are often inaccurate and require manual correction to ensure proper gameplay.
