Display

Each pixel in a color rendered image consists of three values or channels. Each of the three channels represents the amount of red, green, or blue in the image. Maya image files also contain an alpha channel (or mask channel) which represents the presence and opaqueness of objects, and a luminance channel which represents the intensity or brightness of the image.

You can display each of these channels individually as planes using the options on the Display menu. If you are in the scene painting view, the values that display are for the snapshot of the view, not just the rendered strokes.

Red Channel

Display the red values channel for the image.

Green Channel

Display the green value channel for the image.

Blue Channel

Display the blue value channel for the image.

All Channels

Display the red, green, and blue channel planes.

You can also use the Display RGB Channels icon on the toolbar.

Luminance

Display the luminance values channel for the image.

Alpha Channel

Display the alpha values channel for the image.

You can also use the Display Alpha Channel icon on the toolbar.

Note: Alpha channels for the scene painting view are completely white. To see the alpha of the scene painting view, render the scene (Render > Render Current Frame) and in the Render View, select Display > Alpha Channel.

Toolbar

Use this to turn on and off the display of the Paint Effects panel toolbar. See also Paint Effects panel toolbar section below.

Stroke Refresh

Zooming, tumbling, tracking, or dollying the scene painting view takes a new snapshot of your scene, rendering strokes according to the options you select on the Stroke Refresh menu. These options include:

Off: Strokes display as wireframe at their display quality when you zoom, tumble, track, or dolly the view.
Wireframe: Strokes display as wireframe at 100% display quality when you zoom, tumble, track, or dolly the view.
Rendered: All strokes render when you zoom, tumble, track, or dolly the view.
Selected Only: Only selected strokes render when you zoom, tumble, track, or dolly the view. Unselected strokes display as Wireframe (100% display quality).
