[Max] I need help! / Re: Why does an empty scene renders slow?

Hi,
and thanks for the reply :-)
I know Corona is a biased renderer and hardly to compare to non-biased renderer. But this behavior becomes really problematic when rendering product zoom animations in high resolution where the mesh takes most of the time only 10% of the whole image. The region selection speeds up the rendering a lot, and we´re talking here about 30-50 times faster, but that´s not usable for animations. And changing the region every frame by hand for hundreds of frames is not working either. And render farms do not support region selections, so they have to render the whole image which increases the costs also a lot.
What I don´t understand is the following: Rendering a single object in high res without region selection takes almost forever compared to the render time with region selection, but the rendered object does not look any different then when it was rendered without region selection. And here is my question: Why does Corona renders the whole screen, even when there is nothing to be rendered and the outcome is´nt any different? Even rendering only the selected object does not make any difference?!
Don´t get me wrong, I´m not complaining about Corona at all! I just think there is still room for improvement. And increase the render speed in such situations about 30-50 times seems to me worth the time :-)
Best regards,
Nupsi
