Control Input Layer Name Field Description Displays the name of the input image node. By blanking it out, the node is disconnected, but the layer information remains. Composite Mode Disconnect Node This pop-up menu lets you set each layer with its own composite mode, which affects how that image's color data interacts with other overlapping layers. Certain composite modes add parameters to that layer's parameter subtree. For more information on composite modes, see "Supported Photoshop Transfer Modes" on page 476. Clicking the Disconnect Node button disconnects that input image from the MultiLayer node, and removes it from the layer list without removing the input nodes from the node tree. In the subtree of a layer, you can controls its parameters. Note that the parameter names are all prefixed by layerName_ (L1_ in the following image). The only tricky parameter is channels-it determines what channels get bubbled up from below. For example, to add several files together to fill the matte in a Keylight node, insert all the mattes first, then the Keylight node on top of the list, using "a" as your channel for that layer. To rename a layer, expand the subtree and enter the new name in the layerName value field. clipLayer A pop-up menu that lists all the input layers currently connected to the MultiLayer node. Select which input layer should determine the output resolution. postMMult Premultiplies the node. img The input image for that layer. This is the area that contains the interface controls for that layer's Visibility, Solo, and so on. 482 Chapter 17 Layered Photoshop Files and the MultiLayer Node
