Explanation

The famous $gui expression will return 1 in the graphic user interface mode and 0 in render-side. It’s great to enable heavy node only when rendering on the farm and disable it when you are working.

By using a tcl if statement you can easily switch from one ui value to another render value.

 $gui?1:40 # expr?thenDo:elseDo 

In this expression example, it will give you 40 during render and 1 in  the GUI. The only problem is that you can’t really see anymore what you are doing. The GuiSwitcher give you the ability to switch on/off the GUI to see what you are rendering and set both render value and gui value for any created knobs.
