ShuffleCopy

Note:  Nuke 12.1 introduced a new and improved Shuffle2 node, which makes Shuffle and ShuffleCopy obsolete. Shuffle and ShuffleCopy are still available for backward compatibility if you press X in the Node Graph and enter Shuffle or ShuffleCopy.

ShuffleCopy lets you:

• rearrange up to 8 channels from two images (two inputs). For example, you can use it to combine two separate passes (such as the beauty pass and the reflection pass) into the same data stream,

• replace the alpha with black (removing the alpha channel) or with white (making the alpha solid),

• create new channels.

Channels not affected by this node are taken from input 2, which is considered the main data stream.

To rearrange channels in a single upstream node, Shuffle.

To simply copy a channel from one data stream into another, see Copy.
