How to use Shader Editor for Grease Pencil Strokes and Fills It seems that you can't use the shader editor (formally the node editor) to edit stroke and fills for the grease pencil. Am I mistaken, is there a way to edit these strokes and fills as you would a regular material?
You can't, found this on the official documentation.


  The shader is not yet a BSDF capable shader to interact with Blender lights and can only be setting up on the Material Properties panel (it is not a shader node).

Hope they add it soon.
