Quite impressive pathtracing!

Cleans up fast! Seems very interesting, will download it and take a closer look I think.

Keep in mind that it's not pure path tracing; there is still a light cache type of thing going on...

Best regards,

Sure is. But it looks fast nevertheless It looks better, than gpu test scene. I think it should be reworked.

Yes, I agree. I'll get back to it sometime...

Progressive rendering does look fast in the sense that you get to see an image right away - which is the main reason V-Ray RT works this way and why we are doing the same thing for the production renderer in V-Ray 3.0 (although getting a clean final result might be a different matter altogether). With the buckets, you never get to see a full image until all buckets are complete, and as you know some can take a very long time.

Being close to Corona development, while i agree it is really fast renderer, Vlado is right that it is not pure PT. Secondary GI solution is indeed something close to Light Cache. Bucket rendering has it's benefits too, as you can easily find noisiest spot on your image, tweak settings using small region, and then let image render, and you will be always sure that it will come out clean, especially when rendering anim sequences of larger project. With progressive rendering, you always have to take a guess on amount of time or passes needed, and your guess might not always be right

I use both renderers, and i see a great potential in Corona, but at the moment, Vray is far more production-scenario-proof renderer

That being said, i encourage everyone to give Corona a try

yeah nice render speed and stuff looks nice too. Interesting to dig it a bit more...how come its free?

[LudvikKoutny]

It's free now, because it's still alpha version. It would be extremely unfair to charge money from people, who are helping to improve products by sacrificing their time hunting down bugs and proposing feature improvements as well as charge money for an unfinished product... only Autodesk does that! It is planned to go commercial once production ready, but pricing should be very affordable...

[Morbid Angel]

cool stuff...will be looking at the renderer a bit more

i like the idea of a path tracing -lc option. they have some nice options.

it seems though this scene uses partially cached gi?
(from their forum: "Just to clarify, the rendering runs in a partially biased mode with partial caching enabled, it is not pure path tracing nor unbiased.")

inhouse i tested a more or less similar setup, no chaching , vray is doing it in 50sec looking quite similar result, irlc+de (i know no real comparison,but looks same), about 4,46min with brlc.

[Undersky]

Looking cool. 03:10 min here with my double Xeon E5-2687W 0 @ 3,01GHz.
But if it's some LC going on, it's not quite as interesting. It's still impressive, but it would be nicer if I'd have a 100% flicker-free frame rendered after 3 minutes.

[lllab]

it is lc AND parts of gi cached, so in reality will be quite longer i guess

[LudvikKoutny]

Nothing is pre-rendered... cached means interpolated, not path traced, so yes, biased GI solution. But no parts of the solution are pre-rendered and baked.
