Creating photorealistic content in Glossi starts with a high-quality 3D model. If you're using KeyShot, this guide will walk you through exporting your model as a USD file, optimized for use in Glossi. We aim for a perfect balance between stunning visual fidelity and manageable file sizes, ideally below 80MB.
Prerequisites
KeyShot Version: Ensure you have KeyShot version 10.1 or higher. For the best experience and access to the latest USD features, we recommend using the latest version of KeyShot.
Preparing Your Model for Export
It is best to only export what you need for your model to look great in Glossi. So any internal meshes that will not be seen in the final render, consider removing those to conserve file size. This may also remove materials used by those meshes, further reducing file size. Just be sure to save a copy of your full project first.
If your model is a NURBS mesh, you can use the Re-Tessellate Tool to lower polygon density.
Select your mesh then navigate to Tools > Geometry Tools > Re-Tessellate
Lower the Tessellation Quality
We suggest starting at 0.1 and raise (or lower) if necessary to get the fewest polygons while still maintaining its shape and hit Apply. NURBS re-tessellation is reversable so don't worry about ruining your beautiful model.
If your model is not a NURBS mesh, you can still lower density by using the Mesh Simplification Tool.
Select your mesh then navigate to Tools > Geometry Tools > Mesh Simplification
Once KeyShot finishes analyzing your mesh, a window will open with a slider controlling your target number of triangles. Play with this number until you get a more lightweight result that still matches your desired shape.
We suggest doing this one mesh at a time instead of selecting all meshes in the scene. Not every mesh needs the same level of simplification.
Unlike Re-Tessellation, this process is destructive, so save before committing.
USDz Export Overview
KeyShot simplifies the USDz export process by baking materials and textures into a single PNG texture file. This method combines various material properties into one compact file, streamlining the export for Glossi.
Exporting Your Model
Navigate to File > Export > Export to AR (.usdz, .glb)…
Name your file and select a save location.
Export Options
Size: Define the scale of your geometry if scene units are not set.
Texture Resolution: Adjust DPI according to your model's scale. Higher DPI values improve texture detail but increase file size.
Keep Original UVs: Uses the models existing UVs to bake the texture. If your models UV layouts were not created, choosing this will result in improperly baked textures.
Include Ambient Occlusion: Enables ambient occlusion in the texture bake for enhanced depth and realism.
Number of Samples: Controls the precision of the texture bake. Avoid low values to prevent noise; higher values improve quality but extend export time.
Geometry Nodes or Textures Preference: Due to format limitations, prioritize between geometry nodes (like bubbles or displacement) and textures on parts with both.
Recommended Settings:
To ensure your model looks great and performs well in Glossi, consider the following settings:
DPI: 400 dpi works in most cases. Consider lowering only if you've already optimized your model's polygons and still need to lower file size.
Keep original UVs: Only choose this if you have unwrapped all of your UVs. If not, leave this unchecked.
Include Ambient Occlusion: Use this at your own preference. In some case this can cause darker then natural shadows. Consider leaving unchecked.
Compress GLB/GLTF using Draco: If you took the above steps to prepare your model, this should be unnecessary. Leave unchecked.
Number of Samples: Choose between 16-64 samples. This affects the texture bake quality; more samples mean higher quality but longer export times.
Choose Prefer Textures
Once exported, your USD file is ready to be uploaded to Glossi. Ensure the final file size is below 80mb and adjust your settings if necessary to meet the size requirements.
