I know you can append materials but can you append compositing nodes?
I do not know the difference of append and link. If you want to move nodes from blend file to blend file yes you can. group them first. select all. It wont let you do render layer node. control G to group. Save blender file. Then go to file - append - find the save blend - look for the group. you can give it a name before you save it.
Group your nodes, then append the group from your new blend file. After that, in the compositor, Shift+A to add, select Group… and you should see the group of nodes you just imported.
Thanks! Both of you…
