I have asked for the same info in AREA Forum. No reply....yet.
I always find YouTube troublesome with specific questions.... like finding a needle in a haystack.
This is something the Corona Team need to take on board :)
Because Corona does everything staight out of the box there is no room to discuss tweaking. But, since everyone is a Max user the two go together like bacon and eggs.... it makes sense to go to one place.
What I mean is to create a big user base it would be good for Max+Corona users to be able to go to one place only... instead of having to go from one forum to the next.
Just a thought. Your fourm is beautifully laid out and easy to use... I would rather go to a place that cheers me up....
AREA is pretty much dead since they updated their boards/login system, wouldn't use it anymore quite honestly (its what turned me away after being an active user for 2 years).
As per modeling issues, I always find getting advice on online forums is quite hard as either the board isn't populated enough or people are lazy and just don't care to reply. Aside from online tutorials, I suggest finding a good book for reference.
Also while I enjoy the idea of people helping one another out, this is first and foremost a Corona forum, so I don't expect to find help on topics outside of the render engine or render theory here. I'd go to CGSociety, Ronen's board or CG Architect for that stuff.
