Using the Inspector

The inspector panel on the right side of the window gives access to material editing, stage metadata, and animation controls for your loaded model.

Showing and Hiding the Inspector

Section titled “Showing and Hiding the Inspector”
  • Click the Inspector button in the toolbar
  • Or press ⌘I

Materials Section

Section titled “Materials Section”

The Materials section lists every material in the loaded model. Click a material to expand it and edit its properties. For details on individual inputs and format conversion, see Editing Materials.

The inspector updates to reflect the selected object when you click something in the viewport.

Material Properties

Section titled “Material Properties”
  • Color / Diffuse: Base surface color or texture
  • Metallic: How metallic the surface appears (0 = plastic, 1 = metal)
  • Roughness: Surface smoothness (0 = mirror, 1 = fully diffuse)
  • Normal: Normal map for surface detail without changing geometry
  • Emissive: Self-illumination color
  • Opacity: Transparency (1 = fully opaque)
  • Occlusion: Ambient occlusion map

Material Format

Section titled “Material Format”

Gantry shows which material format each material uses — USD Preview Surface, MaterialX, RealityKit, or OpenPBR. The “When editing” dropdown controls whether edits preserve the original format or convert to a different one.

Stage Properties Section

Section titled “Stage Properties Section”

The Stage Properties section at the bottom of the inspector shows scene-level USD metadata and lets you edit it directly. Changes are written as an edit layer and can be undone with ⌘Z.

Up Axis

Section titled “Up Axis”

A segmented control lets you switch the stage’s up axis between Y and Z. Most real-time engines (including RealityKit) expect Y-up. If your model appears lying on its side, switching to the correct up axis will fix the orientation.

Meters Per Unit

Section titled “Meters Per Unit”

Sets the scene’s unit scale as a decimal value (e.g., 0.01 = centimetres, 0.001 = millimetres, 1.0 = metres). RealityKit expects metres (1.0). If your imported model appears very large or very small, adjusting this value corrects the scale.

Default Prim

Section titled “Default Prim”

Sets the USD stage’s default prim path — the root prim that consumers of the file will reference when no explicit path is given. Enter the full prim path (e.g., /Root). This is required for USDZ files that are referenced by other assets or loaded in Reality Composer Pro.

Runtime Capabilities

Section titled “Runtime Capabilities”

The Stage Properties section also displays the runtime capabilities detected on your machine: Hydra renderer, MaterialX, OpenColorIO, and ImageIO support. These are informational and reflect what is available for preview on the current system.
