Render GLB jewelry models online

Why GLB is the best upload format

• One file. Everything travels together, so nothing goes missing between your computer and the studio.
• Compact. Binary storage keeps files small, so they upload and open quickly.
• Names survive. Object names are kept, and the studio uses them to tell stones from metal.
• Widely supported. Blender, Rhino, Cinema 4D, 3ds Max and many other tools can export it.

If you have a choice of export format and you are not using Rhino's own 3DM, choose GLB. Files can be up to 100 MB.

What the studio uses from a GLB file

The studio reads every mesh and its name. Parts whose names contain Diamond, Gem, Stone, Ruby, Sapphire, Emerald, Pavé, Halo or similar words are treated as stones, and the rest start as metal. The studio then applies its own jewelry materials, so you do not need perfect materials inside the file. Good names matter far more than good materials.

How to export GLB from popular tools

Blender. Use the glTF 2.0 exporter and choose the binary GLB format. Apply modifiers in the export options and export only the jewelry, not helper objects, cameras or lights. See the Blender page for detailed settings.

Rhino. Recent versions of Rhino can export GLB directly from the export menu. Select the finished jewelry, export the selection and keep each stone or group of stones as a separately named object. Many Rhino users simply upload the 3DM file instead.

Other tools. Cinema 4D, 3ds Max and most modern 3D tools offer a glTF or GLB export option. Look for binary or GLB in the format list.

Mesh tips for clean renders

1. Keep stones as separate objects. A diamond merged into the metal becomes one part, and it cannot get a gem material on its own.
2. Apply transforms and modifiers before export so the shape in the studio matches your design.
3. Check normals. Inverted normals show up as dark or see-through patches. Recalculate them in your 3D tool if a surface looks wrong.
4. Watch the triangle count. Around 300,000 triangles is plenty for a typical ring. Very dense pavé can go higher, but lighter files are smoother to work with.
5. Remove hidden objects such as old versions of a part, cutters and reference shapes.

Troubleshooting

• A part is missing. It may have been hidden or excluded during export. Check the export options for selection and visibility settings.
• Stones look like metal. Their names did not contain a stone word. Select them in the studio and apply a gem material, or rename them in your 3D tool and export again.
• The model is tiny or huge. That is fine. The studio frames the camera automatically, whatever the units.
• The surface looks faceted. The export used too few triangles on curved parts. Increase mesh density or enable smooth shading before exporting.

GLB or glTF?

Both are the same standard. GLB is the single binary file, while glTF is a text version that can either embed its data or point to separate files. A single-file glTF upload is packed into GLB automatically, but a glTF that relies on separate .bin or texture files cannot be read from one upload. GLB avoids that problem completely. Read more on the glTF page.

From GLB to finished images

Upload the GLB to your library, where a preview is created at once. Open it in the studio, confirm the stones have gem materials, choose metal, lighting, background and pose, then export stills up to 8K or a 360° video. For a full preparation checklist, see preparing jewelry CAD for rendering.
