What's with Corona users and rendering food, now I am hungry again ;).

It's probably because they spend whole day rendering and they forget to eat, so that's what their brains do to trick them.

Yup, it is powerful, but vray's interface makes it hard for a new user to understand.

Yeah, me too. Still more user-friendly than v-ray's DMC sampler settings.

But "deterministic Monte Carlo image sampler" sounds more badass. ;)

(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?


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 ( ). 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)?

Does it have any disadvantages?

Great, photographic quality...
I think resetting Xform sometimes helps with procedural maps issues.

Maybe use sky without sun?

Well I haven't saved it.... I'll rebuild it to try and reproduce the situation, just give me a second..(one more thing, don't know if it's already listed but if I have opened a scene and I click new scene then in max2012 64bit corona legacy build alpha v3 default settings of corona gets screwed(values etc are non default and i have to quit and start max again to get corona to defaults)).
For me, loading scanline as active renderer and then loading corona again without restarting whole max works just fine.

[Max] Resolved Feature Requests / VFB history + comparison

Useful feature: duplicate vfb window with current render to compare with next one. Or you could make a fancy little button to select some region and display previous render inside it.

Why would anybody set sun size to 0.05? :O

Maybe you should show material settings?

I thinks it's a matter of some "threshold". But don't know which one. :)

They are reflecting sky, right?

Anyway, great render. I like its mood, but in this case some kind of volumetric fog would be really useful. You could also make it more "photographic" by adding motion blur to the girl's hands. But maybe this would be too much. Less = more. :)
