Adding a Mask
 
 
 

When you add a GMask node to the schematic, it is added with an Axis node.

To add a GMask node:

  1. Do one of the following:
    • Drag the GMask node from the node bin and place it in the schematic.
    • Drag the GMask node from the node bin and place it in Result view.
    • Double-click the GMask node.

    A GMask object (called gmask1, by default), with its parent axis, appears in the schematic. Once you have added the object, you can create the mask. See Creating a Mask.

Adding a GMask node to the schematic will apply the mask to the entire scene. You link the GMask object to specific media to apply a mask selectively. You can also apply a link to exclude a mask.

To apply selective masks:

  1. Add a GMask object to the scene. All media is affected.
  2. Select GMask from the Edit Mode box.
  3. Do one of the following:
    • To apply a mask to an image, click the GMask node, and drag it to an image you want masked.

      The selected image is connected to the mask by a blue line with an arrow, and only the selected surfaces are masked.

    • To exclude a mask from an image, hold the Alt key while clicking and dragging from the GMask node to the image you do not want masked.

      Excluded images are connected to the mask by an aqua dotted line with an "X", and they are not masked.
