So - if many different shaders define the same material, it follows that there must be some mathematical equivalence going on between them.
When someone is aware of these, they can make progress toward a goal by choosing any of thousands of different changes to the shader.
When someone is unaware of these equivalences, they often make shader changes that have NO impact on the resulting material.
I did six shader changes here on purpose, but lots of people do this by accident. After an hour of twiddling, they're back to where they started and half the nodes don't do anything.
Something to keep in mind.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
