AI 3D Models in Game Engines
Getting AI-generated 3D models into Godot, Unity, Unreal and Roblox: file formats, import settings, and what to fix first, for any generator.
These guides cover what any AI-generated model needs before it works well in a game engine, whichever generator produced it. For a specific generator’s own plugin, its official documentation is the best guide; these pages deal with the cross-tool questions that documentation doesn’t answer. They are based on engine documentation. We have not yet run our own import checks.
Before importing, clean up the mesh, rig it if it’s a character, and check it against your target with the polycount and texture budget calculator. Godot, Unity render meshes and Unreal have no published budget, so for those it asks for yours.
