From Rhino to render: a fast jewelry workflow

Why a repeatable workflow matters

The first render of a new ring is always slower: you choose materials, try lighting and find the right angles. What separates fast studios from slow ones is that the second, tenth and hundredth renders reuse those decisions. A repeatable Rhino-to-render workflow turns rendering into a short routine at the end of every design.

This workflow uses Rhino, and it works the same way for MatrixGold, which runs on Rhino.

Step 0: Build a template file

Start every design from a Rhino template that already has the right setup. Set the units to millimetres, create the standard layers with clear names, and save your preferred mesh settings. When every file starts the same way, every export behaves the same way, and you never have to remember the details under deadline pressure.

Step 1: Organise layers in Rhino

Good renders start with good layers. Use one layer per material or part:

• Metal parts by function: Band, Head, Prongs, Gallery.
• Stones by role and type: Center diamond, Side diamonds, Pavé, Sapphire accents.

Put the material in the name. When you upload a 3DM file to RenderMyJewels, layers whose names contain words such as Diamond, Gem, Stone, Ruby, Sapphire, Emerald, Pavé or Halo are treated as stones automatically, and other parts usually start as metal. Keep those words off metal layers: a metal halo frame is better named Frame.

Step 2: Clean up the model

Before export, remove anything that should not render:

1. Construction curves, guide geometry and dimensions.
2. Boolean cutters and stone cutters.
3. Hidden duplicates and old versions on hidden layers.
4. Printing supports and sprues.

Check that stones are closed, that prongs touch stones without cutting through them, and that normals face outwards. See how to prepare jewelry CAD for rendering for the full checklist.

Step 3: Choose 3DM or GLB

Both work well. Many jewelers upload 3DM for speed and switch to GLB for very detailed pieces where they want to tune the mesh themselves. See the format pages for 3DM and GLB.

Step 4: Mesh for render (GLB)

When you export GLB, Rhino converts NURBS surfaces into triangles. Curved, polished surfaces need enough triangles to stay smooth in reflections. Use a custom mesh setting with a smaller maximum angle and edge length for the band and head, and keep the file reasonable. Most rings stay well under 300,000 triangles without visible faceting.

Step 5: Name files for bulk upload

File names can carry your SKU. In RenderMyJewels, a file named RG-1042_Solitaire.3dm becomes a model called Solitaire with the SKU RG-1042, so a whole folder of exports arrives organised. Pick one pattern, such as SKU, underscore, name, and use it for every export. Uploads are unlimited on every plan, and the bulk uploader takes a whole folder at once. See the model library and bulk upload.

Step 6: Upload and check

Upload the files and let the previews appear. Open a model and check three things before anything else:

1. Stones were recognised as stones.
2. The size and orientation look right.
3. No parts are missing or doubled.

Step 7: Materials

Assign metal and gem materials by layer. Start from presets rather than mixing materials by hand: there are 98 metal and 58 gem presets. For two-tone designs, select the head and shank layers separately and give each its own metal.

Step 8: Lighting, background and ground

Choose a metal environment for the band and a gem environment for the stones, from 64 and 18 options. Pick a background from 28 presets and a ground style from 10, from no ground to soft contact shadows and mirror floors. New models open without a ground, so add a shadow when you want the piece anchored.

Step 9: Poses and exports

Use the one-click poses to set up the standard angles, and save your own. Then export:

• stills in eight aspect ratios at 1K, 2K, 4K or 8K, or a custom size, as PNG or JPEG,
• several saved poses in one go, downloaded together as a ZIP of images,
• 360 turntable or multi-angle videos at up to 4K, saved as WebM,
• variants for each metal or stone option, saved on the same model.

Step 10: Add AI images and video

Use your best export as the input for an AI photoshoot on a hand or neckline, a styled product scene or a short AI video clip for social. See AI jewelry model photos.

Quality checks before you publish

Before images go live, take a minute for a final check. Look at the hero image at full size and zoom into the stones and the setting. Make sure no stone renders dark, no prong cuts into a stone and no part of the piece is cropped. Put the colourways side by side and check that only the metal changes. Finally, view the image on a phone at the size customers will see it. These checks catch almost every problem before a customer does.

Get client approval before casting

For custom work and new collections, you can show a design before it is made. Send a still or two, or share a link to an interactive 3D viewer so the client can rotate the piece themselves. See share links and the 3D viewer. Approving from a render avoids casting a piece that then needs changing, which saves both metal and time.

Exporting a whole collection

When a collection is finished, export every design from Rhino in one session using the same naming pattern, and upload the whole folder at once. Then work through the models one by one with the same house look, applying the same scene preset or the same environment, background and ground choices to each, so each one only needs materials, a quick check and exports. Doing the setup once and the routine many times is what makes the workflow fast.

Keep a house look

Speed comes from reuse. Once a combination of lighting, background, ground and poses works for your brand, write it down and keep it. New models open with the studio defaults, so picking the scene preset closest to your look applies the environments, background and ground in one click. Each new model then needs only materials, a quick check and exports. A consistent look also makes your catalogue feel premium, because every product sits in the same visual world.

Keep source files and exports together

Keep the Rhino source, the exported 3DM or GLB and the final images in one folder per SKU on your own drive. The uploaded original stays in your RenderMyJewels library too, and you can download it again at any time from the model's menu. When a buyer asks for a variation months later, everything you need is in one place.

Handling design changes

Designs change after client feedback. Export the revised file with a version in the name, such as RG-1042_Solitaire_v2.3dm, and upload it as a new model. Move the old version to the trash when you no longer need it. Deleted models stay restorable for 30 days, so nothing is lost if you change your mind.

Troubleshooting

Summary

A fast Rhino-to-render workflow is mostly preparation and reuse. Start from a template, name layers by material, clean the model, export 3DM or GLB with SKU-based file names, check the upload, then apply your house look and standard poses. After the first model, each new design becomes a quick routine.
