At 5:22 the separate XYZ node is dropped and it creates a line out to somewhere....but where?
Hi Lisa,
That line was already there, it goes directly to the Surface of the Material Output Node (via a hidden Viewer Node, that is just an Emission Node).
You mean when he drops the node up top the noodle? It does that automatically, it'll just plug it for you. Unless that isn't what you mean?
