I ask concrete question and try to get concrete answer. Your mind about reading the books and my 40+ projects just not useful. Sorry.
Your answer about using pure white reflection color looks just wrong.
My workflow must be effective. Only this way I can manage my 40+ projects, which you can't forget.
If we have new material concept here, I need to learn it. It's a reason why I ask. There is not documentation about. Usually I use IOR and LRV numbers from catalogs and manage only glossy. With your workflow I don't see for example, where to put LRV.
Once more - I'm not a big artist. 99% of users - you'll be wonder - are not big artists. And rendering - you'll be wonder - it's not art only. But I read a lot, have some knowledges, have some experience and my business works good. Because I don't try to look a guru and don't hesitate to ask may be stupid question.
So my question is still actual. Do we deal with new concept (pure white reflection color and so on) or you just mistaken and I may to continue work as in the past.
Simple question - I'm waiting for simple answer. Your answer "go and read the book" I already know.
You seem to ask the same thing over and over again and it seems you're afraid of doing something wrong. Here's a little secret that you may not be aware of: Corona, being a 'physically accurate' renderer, follows the law of energy conservation which means that all of the materials you create are physically correct (or physically plausible). However, no one can teach you how to setup EVERY material correctly to work in ANY condition you may think of.
Really, sit down in front of your PC and spend time learning for yourself instead of trying to suck out others' brains. Chances are that - even if people tell you the value of every parameter in their materials - you won't like the result or will have to adapt it to your lighting and general setup. It may sound stupic but you need to find a way that works for you.
Why not just plug a map into the glossiness slot, play around with color correction and see where it gets you? Hint: this was an example, don't take it too literally.
If you try to dissect every suggestion given to you by different people, you will find that every one does things differently, yet they all produce beautiful work. There's no wrong, just go ahead and try, but stop accusing people of being arrogant when they actually try to help and it just doesn't happen to click in place for you.
