(not sure if this belongs here or to "tutorials and guides")
I'd like to ask some questions that would clarify my vision of how Corona works. I think they might be obvious for those who have more theoretic knowledge about rendering systems, but I'd really like to know this. Maybe other forum users have similar questions so this thread might serve us as noob centre. And yeah, Keymaster, I promise some day I will read whole your Bachelor and Master Thesis. :]
1. When I use HD Cache only, rendered image comes out as a mix of random paint-like splotches all over the scene. I bet that's how it works, pretty much like Light Cache in vray, right? Averaged samples from a certain radius?
SO
What happens when I use Path Tracing + HD Cache? Does it use data collected from HD Cache to speed up path tracing? What's that green-coloured stuff shown in precalculations? Areas that are considered too important and will only use path tracing?
I'd also like to know how certain "thresholds" work. To make the GI calculations more precise and slower, should I lower some parameter, or make it higher. For example:
-Interpolation sensitivity (dir/pos/norm) - I bet making them HIGHER than default values will make HD Cache calculations more precise OR will force it to use Path Tracing in more areas (?).
-Glossy threshold - lowering it will make reflections use less HD Cache and more PT thus making them more precise?

Oh, and one "bug" about the Corona Render Settings website (
http://corona-renderer.com/doc/ ). It's neat, but when I scroll down and want to read about some values that are listed at the bottom of the page, the popup frame doesn't fit on screen and I can't see lower part of it. Maybe it's a matter of my browser (Firefox) or screen resolution (1680x1050)?
