Hasta La Motion!

Hey people, this is a very beginner question but I’ve searched every forum I could find that mentions Nuke’s relight tool.

Simply put, I can’t find where mine is. I can’t bring it up with tab or execute it with shortcut x or find it in my menu bar. Most tutorials I’ve seen assume that you have it. I saw in two forums passing references on how the node is "hidden because it’s not fully supported".

I have Nuke 6.1v3 on a vista x64 bit and so I have the relight node if it isn’t hidden. If it is, can someone please give me a quick tutorial/link on how to enable this node? Thank you for your replies in advance!
