Render Sequence: Define how the alpha key signal should be generated (default is Overlay):

• Virtual Studio: This option is relevant only in combination with Viz Virtual Studio. This mode switches from Overlay to Full Screen when the control mode of the current camera switches from Remote to Editor (see Camera Editor). In a Virtual Studio set, to do a camera flight with the virtual camera, when the real camera is stationary, the graphics must be set to Full Screen to avoid a situation where the virtual and the real camera have different position values. When the camera is switched from Remote to Editor (to do the flight) the keyed graphics automatically switches from Overlay to Full Scree.

• Full Screen: When Render Sequence is set to Full Screen, downstream compositing is enabled and will generate a full screen key that outputs a non-transparent key signal. This means everything without a Key plug-in will be treated as background graphics and appear behind DVEs on the output. Everything with a Key plug-in will be rendered in front of DVEs. For setups using a Matrox X.mio video board, the key preview is all black, instead of all white, while show key is enable in the scene editor. This allows the designer to work with containers with Key plug-ins during scene design.

• Overlay: Set as key signal only those Containers that have a Key function applied. Only Containers in the Scene Tree with a Key function applied are rendered into the key signal. Use this mode to correctly blend graphics and DVEs.

• Auto Key: This is the preferred mode for overlay graphics. The key signal is automatically generated from the Containers in the Scene Tree, it does not require the application of Key functions to the Container. This function provides a worry-free overlay.

• Background Image: This option is only applicable if a background image with an alpha layer is added. The alpha values of the background image are used as a key signal and Containers with a Key function applied will be rendered on top.

• Libero: The render sequence for a Viz Engine used in with Viz Libero (see Viz Libero and Viz Arena Render Sequences).

• Arena: The render sequence for a Viz Arena/multi-zone keying setup (see Viz Libero and Viz Arena Render Sequences).

• Arena/Libero: The render sequence if the tracked camera is a Viz Arena image tracker (see Viz Libero and Viz Arena Render Sequences).

Key Render Mode:

• Config: Render the key according to the settings in the Viz Configuration.

• Single Pass: Use one rendering step. Use this for all new scenes and for scenes imported from version 2.8, as it is much faster.

• Double Pass: Use two rendering steps. Use for backward compatibility in scenes created in Viz Artist versions 3.0 to 3.3.

Background Color: Set the color of the background.

Image and Media Asset Placement:

• Background: Add an image or Media Asset as the Scene background.

• Foreground: Add an image or Media Asset as the Scene foreground.

  Note: If the foreground image or Media Asset has alpha, the Scene can be shown through the image or Media Asset.

• Preview: Add a fixed layout to the Scene. This visualizes how the total preview (camera picture and/or graphics/Media Asset) will look like. To set the image as global default, click the Set Default button.

  Tip: It is possible to drag results from a database search onto the Background, Foreground, and Preview drop zones.

Stereo Mode: (license required) Select the correct stereo mode for the inserted image (not available if Stereo Mode is set to Off in the Viz Configuration (see Camera in Viz Configuration):

• None: No Stereo mode.

• Config: Images are drawn as set in the Viz Configuration (see Camera in Viz Configuration).

• Over Under Left Top or Over Under Right Top: Two images are stored, one over (top) and the other under (bottom), left or right eye (top) first. The image height will be halved, providing half resolution.

• Side by Side Left or Side by Side Right: Two images are stored, side by side, left or right eye first. The image width will be halved, providing half resolution.

  

Mask Invert: Makes it possible to set one or more of the mask layers in a Scene to be inverted. With no mask inverted (1), the mask cuts out a hole where it covers the mask target object. With mask invert enabled (2), the mask target is only visible where the mask covers it:

Shadows: Enables or disables the shadow function in a Scene. The shadow function uses two layers from the mask function. With shadows enabled, there are only six layers available for the mask function (see Mask Source and Mask Target). In a scene where more than six mask layers are needed, shadows can be disabled (only very complex mask configurations need more than six layers).
The Stencil shadow type is the least resource-demanding way to render shadows in scenes. For more advanced and better-looking shadows, cascaded shadow maps can be enabled. For more in-depth information on shadows in Viz Artist, please refer to Shadow Maps and Shadow Caster and Shadow Receiver.

Magnifier: The magnifier acts on the last rendered surface. It can be either a rectangle or a circle. The position and size is defined in normalized view-port coordinates.

• Active/Inactive: Set the magnifier to active or inactive.

• Type: Select a Rectangle or a Circle for the magnification area.

• Tesselation: Set the tessellation, if Circle is selected.

• Transformation: Set the parameters for the Position, Size, Scale and Ellipsis of the magnified area.

• Color: Set the alpha and the color of the magnified area.

• Container: Select a Container to control the position and, or, the scale of the magnifier. Type the name of the Container in the box. Select On or Off for Use Position and Use Scaling.

  
  

Stage Show Mode: Defines how the STAGE*SHOWMODE Viz Engine command should be handled for the scene. The command takes a named stop point or tag as a parameter, and the show-mode defines how the scene will be executed.

• Selected: Sets the time-line of all selected directors to the first found tag location. This is the default setting.

• First: Sets the time-line of the first found director, containing the searched tag, to the tag's position.

• Separate: Positions the time-line for each director, containing the searched tag, to the tag's location.

Tree Color Text: Define custom text labels for the scene tree colors in the current scene. To define global labels or custom colors, go to Viz Configuration -> User Interface -> Colors (see the Viz Engine Administrator Guide).
