These define when the shutter of the camera will open and close; this will affect Exposure and Motion Blur.
If the camera is stereo, this defines the center of role for the two cameras, left, center, or right.
Control Visibility
This section allows you to selectively activate the onscreen controls that are displayed along with the camera.
— Show View Controls: Displays or hides all camera onscreen controls in the viewers.
— Frustum: Displays the actual viewing cone of the camera.
— View Vector: Displays a white line inside the viewing cone, which can be used to determine the center of the frame.
— Near Clip: The Near Clipping plane. This plane can be subdivided for better visibility.
— Far Clip: The Far Clipping plane. This plane can be subdivided for better visibility.
— Focal Plane: The plane set by the Focus Distance. This plane can be subdivided for better visibility.
— Convergence Distance: The point of convergence when using Stereo mode. This plane can be subdivided for better visibility.
Common Controls
The Transform and Settings tab in the Inspector are also duplicated in other USD nodes. These common controls are described in detail at the end of this chapter in “The Common Controls” section.
uImage Plane [uIm]
The USD Image Plane node
uImage Plane Node Introduction
The uImage Plane node produces 2D planar geometry in 3D space. The node is most commonly used to represent 2D images on “cards” in the 3D space. The aspect of the image plane is determined by the aspect of the image that is input.
Inputs
The input on this node is for the image that will be texture mapped to the plane.
— Input: The yellow input is used for the connection of a MediaIn image.
Basic Node Setup
The uImage Plane Node accepts a 2D image and places it into a 3D USD scene.

Controls Tab
Most of the Controls tab is taken up by common controls. The Image Plane-specific controls at the top of the Inspector allow minor adjustments.
The uImagePlane has an input so an image can be piped directly into the node. This node can also directly load an image by browsing, and it will show the name and path in the filename. Use the Browse button to open the file browser and select an image.
Size will set the size of the image plane in the USD 3D scene.
