I think this thread has gotten WAY off topic.
The initial post wasn't about making Corona easier. It was helping some of us understand the basic 101's of rendering, color picking, different color selection choices, etc. and the "how" and "why" these things hang together.
Albert Einstein once said, "If you can't explain something simply, you don't understand it well enough."
I'm a technologist by trade. I've architected elegant solutions that were complex in design, but fairly simple to explain to the board of directors who were PAYING for it. 80% of corona users aren't that technically savvy but they're still paying customer and want to become better.
When I read the INITIAL thread that started this post, I saw a messages saying "Pretend that the average Corona user is a guy who doesn't understand all of this stuff by default, but still does (or wants to do) alot of 3D work." Then he went on to say that if the average user can understand some basic fundamentals, the quality of their renders would skyrocket and would better help promote Corona. I saw NOTHING in there that said he wanted CORONA simpler. He want's to UNDERSTAND fundamental concepts THAT MOST OF YOU ALREADY KNOW BY EXPERIENCE, more simply.
The biggest problem (from his perspective) and I happen to agree... is that all you brilliant animators and programmers and artists take for granted how much you know about the basics that you're flying 50,000 feet over the head of the average user who doesn't even know where to begin to look to understand this.
His post, to me, wasn't a request to simplify corona. It was a request to explain some of the more simple concepts that so many of you assume we all know. And, like him, many of us have no idea where to even start to look to find it.
