I have two projects. In one I have a lot of compositing nodes including a lot of render layer nodes. I have found a way to append nodes but it does not work with render layer nodes. Is there a way to append compositing nodes including the render layer ones? It would take me ages to copy that and yet it would not be the same. Thank you very much.
Append a Scene
Compositor nodes belong to the Scene settings.
You just have to Append a Scene from a blendile containing the compositor setup you want. Go under -> File -> Append, pick the file and look under the Scene folder.
Then go to the scene selector, open the compositor in the appended one and copy past the nodes in yours.
Remember to update the render layer input scene in the copied compositor node setup.
