Viewport Settings
The Viewport Settings module provides technical controls for how USD geometry is visualized within the Preflight renderer. It allows you to toggle different “purposes” for your prims, which is a core concept in the USD specification.
Visualization Toggles
Section titled “Visualization Toggles”Prims in USD can be tagged with different purposes. This module lets you control the visibility of these tags simultaneously:
- Final (Render): Displays geometry tagged with
purpose="render". This is typically the high-fidelity version of the model intended for the final output. - Preview (Proxy): Displays geometry tagged with
purpose="proxy". This is often a lower-resolution version used for faster viewport performance during layout. - Rig & Guides: Displays geometry tagged with
purpose="guide". This includes control widgets, skeletons, or other non-rendering helper geometry.
Default Geometry
Section titled “Default Geometry”Geometry with no specific purpose (default) is always visible, regardless of these toggles.
Use Cases
Section titled “Use Cases”- Proxy-to-Final Comparison: Quickly toggle between proxy and render geometry to verify alignment and detail level.
- Animation Debugging: Enable “Rig & Guides” to see the underlying skeleton or control prims while playing back animations.
- Performance Optimization: Disable “Final” and enable “Preview” if you are working with a very large scene that requires smoother navigation.
