Why do I get a red-colored node when copying some nodes from the examples? In this case the [FFTQueue]


I wanted to use the FFT example to assist me in some of my work, but I don’t know why I’m getting that empty/dummy node when copying/pasting it.

Because the FTTQueue of the help patch is a process node that is not yet included in your document.

Go to the document menu and you will see two entries called Application and Definitions. Imagine these two as two sides of your patch, front and back, where front is always the patch itself and the back is where you store your custom datatypes, nodes, functions etc.

You will find a Process definition called FTTQueue on the definitions side of the help patch that you are copying from. Just also copy that to the definitions of your document.
