I wonder what’s the node ‘set clipping planes’ used for?

If you hold your mouse over a Node it will give you its description if available.

This node seems to be used in VR.

Yes,I do see the explanation.However,I still can not understand it.

If you cant determine what it does from the description then you probably shouldnt be using it or worrying about it right now.

The Near and Far Clipping planes determines what is rendered within those parameters.
