Quote - IOW, you've done nothing. Was that your point?
Indeed, that was my point. In this scenario, plugging the color map straight into bump and displacement would do exactly the same thing. The math node isn't doing anything at all that you wouldn't get without it.
Some people may think the math node is doing the conversion to gray scale. Well, it is, but not because it is a subtract 0. It is doing that because you plugged a color into a number. Building a math node just to have a number to plug into is a useless and confusing waste of time.
The bump channel is a number. Plug the color into the number straight away.
The displacement channel is a number. Plug the color into the number straight away.
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)
