Back Plate pane

The Back Plate pane lets you select a background texture (containing an image or video clip) to be displayed on a camera’s background plane.

The background plane is a separate plane used only for projecting images or video clips. The size of the background plane matches the camera’s viewing area and remains a part of the camera’s view, even with the 2D magnifier, and the Turn Table options.

Image Display settings

The Image Display area lets you select how the specified texture is applied to the Back Plate plane.

Note: The default Image Display settings are Center and Maintain Ratio.

Choose the following options from the Image Display area:

Option	Function
Fit	Scales the background texture to fit on the background plane. If Fit is disabled, the Offset X/Y and Scale X/Y options become active (see below).
Crop	Crops the background texture to fit on the background plane. If the texture is smaller than the plane, this option has no effect.
Center	Centers the background texture on the background plane.
Maintain Ratio	Keeps the aspect ratio of the background texture. Activate Maintain Ratio with the Fit option to scale the texture proportionately. Note: When you use this setting, the Scale Y setting is ignored and only the Scale X setting is used.

Offset X/Y

(Only available if Fit is disabled)

Use the Offset X and Offset Y values to transform the plate precisely alongside the Center and Maintain Ratio settings.

Scale X/Y

(Only available if Fit is disabled)

Use the Scale X and Scale Y options to stretch or shrink the plate precisely using the Center and Maintain Ratio settings.

Note: Scale Y values are is ignored when Maintain Ratio is active, and the the Scale X value is used for both axes.

The Distance Mode menu lets you place the background plane in the camera’s viewing area. The Distance Mode menu lets you select whether the background plane is placed in relation to the camera interest or the camera.

The Distance Mode menu contains the following options:

Option	Function
