AI 3D Models for Game Development
Concept art goes in, a textured GLB comes out, and your prototype scene stops being a field of grey boxes. Hi3D is the fastest route from a drawing to something you can walk past in-engine.
Prototyping a level with placeholder primitives tells you almost nothing about how it will feel to play. Real silhouettes, real scale relationships and real surface colour change the answer, but commissioning or modelling every prop before the design is settled is exactly the wrong order of work. Hi3D fills that gap: generate a usable asset from concept art in ninety seconds, drop it into the scene, and find out whether the space works before anyone spends a week on a final model.
Why Game Teams Use Hi3D
GLB Drops Straight Into an Engine
Unity, Unreal Engine, Godot and Three.js all import GLB natively and wire the embedded albedo into the material on arrival. There is no FBX axis argument, no missing-texture pink, no import preset to remember. Drag the file into the project and the asset appears in the scene looking the way it looked in the browser preview.
De-Lit Textures Behave Under Your Lighting
A texture with the concept artist's lighting baked into it fights your scene's lighting forever. Hi3D removes specular highlights and cast shadows before baking, so the albedo carries surface colour only. Your directional light, your ambient occlusion and your post stack then produce the shading, which is the only way an asset ever looks like it belongs in the scene.
Prototype Cost Close to Zero
Because generation is free and takes under two minutes, the cost of trying an idea drops to nothing. Generate five variants of a prop, place them, delete four. Test whether a landmark reads at distance. Populate a blockout with real shapes so playtesters react to the space rather than to the greybox. Assets that survive the prototype are the ones worth building properly.
Concept Art to Engine Asset
Generate From Concept Art
Upload the concept sheet, sketch or reference photograph. Isolated subjects on a clean background reconstruct best, so crop a busy sheet down to one object before uploading.
Export GLB
Download the GLB so the mesh and its albedo travel together as one file. This is the format your engine will handle with the least ceremony and the fewest broken references.
Import, Place, Iterate
Drag the file into your project, set the scale against a character controller, and place it in the blockout. If the silhouette does not read at gameplay distance, adjust the concept art and generate again.
Engine Compatibility
| Engine | Compatibility | Recommended Format |
|---|---|---|
| Unity | Native GLB import | GLB |
| Unreal Engine | Supported | GLB / OBJ |
| Godot | Native GLB import | GLB |
| Three.js | Native GLB import | GLB |
GLB is the recommendation everywhere in a game pipeline for one reason: it is a single file that cannot lose its texture. Multi-file formats break the moment an asset is moved, zipped or handed to a colleague without its sibling files, and that failure mode costs more hours across a project than any import setting. Unreal accepts GLB and also reads OBJ if your existing pipeline is built around it. Whichever you use, set your project scale convention early and check imported assets against a character-sized reference before art starts building on top of them.
Frequently Asked Questions
They are excellent for prototyping, background props and static set dressing, where polygon budgets are forgiving and nothing deforms. For hero assets and anything that animates, treat the generated model as a high-detail reference and build a production mesh with intentional topology and LODs on top of it. This mirrors how studios already use scans and sculpts.
Not directly. The output is a triangle mesh without the quad edge loops a skeleton needs to deform cleanly at elbows, knees and shoulders. The standard path is to retopologise into quads, weight the new cage to your skeleton, and bake detail from the generated surface onto it. For static props, no retopology is needed at all.
You are free to use the 3D models you generate in commercial projects, including shipped games. The one requirement is that you hold the rights to the image you upload — generating from someone else's concept art or a copyrighted product photo does not give you rights to the result. Our terms of service set this out in full.
A single object, filling most of the frame, on a plain background, lit evenly. Three-quarter views reconstruct better than dead-on orthographic ones because they give the model more information about depth. Crowded concept sheets with several objects confuse the silhouette extraction, so crop to one subject per generation and run the tool a few times.
