Viewer inputs
Any Viewer in Nuke has up to 10 different inputs and it's very easy to connect nodes to
these inputs in order to view them. Simply by selecting a node and pressing a number on
the keyboard (like you pressed 1 before) you're connecting the node to that number input
oftheViewer.Thiswillresultinseveraldifferentpartsoftheprocesstreebeingconnected

with ease.
