I am new to Blender, so maybe I'm missing something. I'm an expert 3D user with 30 years of experience. I am having a problem with what appears to be a major limitation of the Shader Editor. Namely, it only displays a single shader tree at a time.
How can I edit the shader tree of more than one object simultaneously? How can I use the Shader Editor to share shading nodes between multiple shader trees?
For basic functionality, I need the Shader Editor to work like industry standard 3D applications. There should be no limitation on the number of material shader nodes, trees, or closures visible in the graph, and no direct relationship between what object is selected in the scene and what is visible in the graph.
I know how to pin the graph so it doesn't follow the scene selection. That's not what I'm asking. In that case I am still limited to a single shader tree.
I searched Google, but could only find results on how to assign multiple materials to the same object. That's also not what I'm asking.
