Reuse Material Nodes between Blend files?

So it seems there's no way to reuse node setups between blend files. I tried appending the node tree setup and then adding a "pointer" inside the node editor, but it does nothing, shows a black material instead. Using Luxcore 2.5 with Blender 2.92

Nevermind, I solved it by appending from the "Materials" folder instead of the "Nodetree" folder
