Image-to-3D generation is only the starting point for a game-ready asset. Before importing the result into Unity, Unreal, Roblox-style worlds, Three.js, WebGL, or a playable prototype, inspect the generated model for scale, pivot, orientation, missing materials, texture references, polygon count, file size, license/source notes, target engine, and export format. Then clean up, optimize, convert, and record limitations instead of treating the first generated file as production-ready.
