Keyshot

This guide walks you through optimizing and exporting your KeyShot models for use in Glossi.

Note: KeyShot models often have dense geometry and duplicate materials that can result in large file sizes. Taking time to optimize before export will significantly improve your experience in Glossi Studio.

1. Prepare Your Model

Start by saving a copy of your KeyShot project to preserve the original file. Then:

• Remove obstructed geometry — Identify and delete any internal geometry that is completely hidden within your scene. This reduces file size and improves performance.

• Try an initial export — Export your model at this stage to gauge the level of optimization needed. In some cases, your model may already be within the file size target.

2. Optimize Materials

Reducing duplicate materials can significantly decrease file size and improve loading times.

1. Navigate to the Material View in KeyShot.

2. Right-click on any duplicate material and select "Link Duplicate Materials".

3. Choose to link all duplicates or specific ones.

Linking duplicates prevents exporting unnecessary textures, reducing the overall file size.

3. Optimize Mesh Density

The approach depends on whether your model uses NURBS surfaces:

If your model uses NURBS:

1. Select the mesh you want to optimize.

2. Use the Retessellate tool under the Tools dropdown.

3. Adjust the Tessellation Quality slider to reduce the number of faces while maintaining the model's silhouette.

4. Experiment with the Angle Tolerance and Maximum Edge Length sliders for further refinement.

If your model uses polygon meshes:

1. Go to Tools > Mesh Simplification.

2. Select your mesh and adjust the triangle count slider to control simplification.

3. Pay close attention to the silhouette as you reduce — this method is destructive, so keep a backup of your original model.

4. Export Your Model

1. Go to File > Export > glb/gltf.

2. Check "Keep Original UVs" if you modified your UV mapping.

3. Select "Prefer Textures" unless you're using geometry nodes.

4. If the file size is still too large, consider lowering the texture resolution in the export settings.

5. Save your .glb file.

Pre-Export Checklist

Before exporting, verify:

• Hidden and internal geometry is removed

• Duplicate materials are linked

• Mesh density is optimized (especially for NURBS models)

• A backup of the original project is saved

• Texture resolution is appropriate for your file size target
