Apple Shake 4 - Manual (Page 461)

Chapter 16 Compositing With Layer Nodes 461
Parameters
This node displays the following controls in the Parameters tab:
clipMode
Toggles between the foreground (0) or the background (1) image to set the output
resolution.
channels
Tells Shake which channels to copy from BG to FG. You can use r, g, b, a, and/or z. To
use multiple channels, list them out. For example, rgz copies the red, green, and Z
channels.
copyBData
If you’re using an image with metadata within the blind data container, you can assign
the blind header data from the foreground input image to the background input
image by turning on copyBData. This can be useful if you have a complex node tree
that uses many layer nodes combining several images, yet you want the final file to
render out with specific header data taken from one of the FileIn nodes.
For more information about custom file header metadata, see “ Support for Custom File
Header Metadata ” on page 178.
IAdd
The IAdd node adds one image to another. The strength of the second image can be
raised and lowered with the percent parameter.
Parameters
This node displays the following controls in the Parameters tab:
clipMode
Toggles between the foreground (0) or the background (1) image to set the output
resolution.
percent
A built-in fade parameter. This is the amount of the second image that is taken into
consideration. Full strength is 100. If set to 50, the added amount is reduced by 50
percent.
IDiv
The IDiv node divides one input image by another input image. The strength of the
second image can be raised and lowered with the percent parameter. To divide an
image by its own matte channel, use the MDiv node.
Parameters
