Duplicating Light effects in Maya

Have you ever tried duplicating a light with light effects in Maya? It never works. Right?

Well here is a cool trick to get it to work.

1. Select the light (with the light effects) in the viewport.
2. Open Hypershade by clicking on Window>Rendering Editors>Hypershade.
3. Click on Graph>Input and Output connections to display the node network.
4. Click on Edit>Duplicate>Shading network
5. That's it! Now the light has been duplicated along with the Optical FX node.
