For MBlend nodes, if the layer has a matte component (that is, there are nodes in the Matte pipe), the
Curves Blend option is selected in the Blend box and the Matte Curves graph is displayed at the right
of the menu.
NOTE If Basic Blend was previously selected, then it is displayed. To display Curve Blend, select it from the
Blend box. The Blend box does not appear for CBlend nodes, since Curve Blend is the only option.
2 Display the Result view. This displays the result for the entire blend node.
3 To perform a logical operation on the front and back images, select one from the Logic Ops box.
4 Use the Blend Curve editor to adjust the front and back matte curves as needed.
Using Several Layers in a Blend Node
You can use up to four layers in blend nodes to create the composite. Using layers, you can avoid doing
multiple passes on the same composite. Layers are processed upwards from the bottom layer. In other words,
the uppermost layer will appear on top of the next layer, and so on.
The back component of the lowest layer is a pure black image (for MBlend nodes) and the node input image
(for CBlend nodes). For additional layers, however, the back component is different. On both CBlend and
MBlend nodes, the result image of the lowest layer is fed into the next highest layer to serve as its back
component. Likewise, the result image of this layer is fed into the next highest layer where it serves as that
layer's back component, and so on.
NOTE The Current Layer proxy does not display the current layer using the result of the previous layer, as described
above. Instead, it displays the layer as if the back clip were a black image (for MBlend nodes) or the front image
(for CBlend nodes).
You can change the order of the layers using the Priority Editor.
To create a new layer:
1 Select the blend node by clicking anywhere in the rectangular box at its right end.
The node is highlighted and the Blend Node menu appears.
(a) Layer Name field (b) Add button
2 Click Add to create the new layer.
A new layer is added to the blend node, above the previous layer. The default name for the new layer
is layer2.
3 Add nodes to the layer as needed.
4 To change the order of the layers, click the
