I don't know if this every went into feature requests, but I'd still very much like either internal node networks expose the Main Input for easy use without users manual interaction of linking shaders, or maybe just the Null Shader allow this for setting up AIO shaders. It would really be helpful without having the user needing to go in and plug their terrain into X shader for my shaders to then use it. That way the user can just plug the null into their shader tree, and I can feed that main input inside the node.
