#b3d tip: To keep complex node trees organised, you can use Node Groups. They reduce part of a node tree to a single node, which you can enter/exit by pressing TAB. You can also create inputs, so that you can control values inside the Node Group without having to... open it.show more

As powerful and specific nodes are I still wish they weren’t so complicated.

I've wondered if there is an easy way to find node groups via search? Sometimes you are seeing someone else's nodes and the groups blend in when they are renamed and have regular inputs and outputs.

How to use reroute nodes? Can some one guide me

You can put a period at the start of the node group's name (like .MyFancyInternalFunction) and it won't show up in the menu or search list. Useful if you made a group just for internal use and don't want to clutter up your menus.
