Help with Shuffle, ShuffleCopy and Copy nodes


I just started learning Nuke and I am pretty confused with these 3 nodes. I tried watching the Node Reference Library from Digital Tutors and I still don't understand it that well.

I get that Shuffle copy is used to copy the RGB values from one pass to another. Is that the only use of the node?

What exactly does these nodes do and how can I use them to make my comp better?

I have seen scripts with tons of these nodes, but I dont understand the purpose.

Please help.

I would first get really familiar with the concept of channels and how Nuke uses them. Once you understand how the channel system works in Nuke, it's easier to get all the different ways to manipulate them.

Check out this blog entry for more detailed info about the nodes. Its kinda old, so the UI is different, but still works the same.

Another thing to note is that quite a bit of the time, a simple Shuffle or Copy is all you need. I see so many scripts where a ShuffleCopy is used unnecessarily when one of the simpler operators could have been used. There isn't necessarily anything wrong with that, but from a learning standpoint it's much easier to wrap your head around Shuffle and Copy first.
