03 / Roji 3D Viewer

Inspect composed USD scenes

The 3D Viewer shows the scene produced by the current graph node. Use it to check geometry, cameras, lights, materials, and selection before rendering.

Viewport

View the current graph state

Open the viewer from the node or viewport area connected to the current graph state.
Use viewport display options to switch between shaded, wire, bounding box, and diagnostic views when available.
Use the viewer to confirm the scene before saving or submitting a render.

Selection

Select prims and inspect paths

Selection connects the viewport, outliner, and inspector. Use it to identify exact prim paths for cameras, lights, and CEL rules.

Select geometry, cameras, or lights in the viewport or outliner.
Use selected prim paths when setting render cameras or light linking rules.
Check imported light names before assigning lightgroups.

Cameras

Check the render camera

A farm render needs a saved camera or an explicit camera prim path. Do not rely on an unsaved viewport-only camera.

Select the camera in the viewer or outliner.
Copy or confirm the camera prim path.
Set that path on the Render node before sending the graph to farm.

Large USD

Work with heavy scenes

For large USD stages, use lightweight display modes while navigating, then switch to richer viewport modes only where needed.

Use bounding box or simplified display while checking layout.
Load detailed views only where the shot needs inspection.
Keep scene checks close to the graph node being rendered.
