Hyper3D AI 3D generation

Have you tried Hyper3D?

Generate 3D models from text or images, and export for games, products, and 3D printing.

Start for Free

Text to 3D Turn prompts into textured model drafts.

Image to 3D Convert product photos and references into 3D assets.

Export ready Move assets into Blender, Unity, Unreal, AR, and print workflows.

AI 3D just hit a new threshold. Rodin Gen-2.5: geometry in about 4 seconds, full model in about 5 seconds, 10M+ polygons, clean structure, and production-ready outputs.

Tested Rodin Gen-2.5 from Hyper3D. Cleaner meshes, sharper surface detail, and stronger multi-angle coherence.

Rodin Gen-2.5 is a meaningful upgrade: 10M+ polygons, 3D-native textures, and strong results on complex high-poly models.

Popular GLTF Viewer Workflows

Preview GLTF files for Web scenes workflows before importing them into another 3D, CAD, print, or real-time tool.

Games

Game Asset Review

Open FBX, OBJ, GLB, GLTF, and texture-heavy assets before bringing them into Unity, Unreal Engine, or a DCC tool.

AR and Product Preview

Inspect USDZ, GLB, and GLTF product models for e-commerce, AR previews, configurators, and stakeholder reviews.

3D Printing Checks

Preview STL, 3MF, OBJ, and PLY files before slicing so you can catch orientation, scale, and mesh visibility issues earlier.

CAD

GLTF Viewer FAQ

Answers for creators, developers, product teams, print users, and 3D artists working with model files in the browser.

How do I open a GLTF file online?

Select the GLTF viewer, upload your file, and the preview opens in a browser modal. You can rotate, zoom, inspect the model, and reopen it later from local history.

Are uploaded files sent to Hyper3D servers?

No. The viewer reads files in your browser and stores upload history in local IndexedDB on this device. The model preview does not require a server upload.

Can the viewer load textures and companion files?

Yes, when the format references companion files, upload the model together with related MTL, BIN, or texture files. Embedded texture formats such as GLB are usually the most portable.

Why does my model appear blank or untextured?

The file may be missing companion texture files, use unsupported material settings, contain inverted normals, or be too heavy for the current device. Try a simpler export or pack textures into GLB.

Which 3D formats does Hyper3D Viewer support?

The viewer supports OBJ, FBX, USDZ, STL, GLB, GLTF, 3MF, PLY, DAE, 3DS, 3DM, STEP, STP, IGES, and IFC for common web, game, AR, print, CAD, and BIM workflows.
