Exterior wip

[Ondra]

12 h for exterior render? Wow, this is too much I think. And still a lot lot lot noise.

BR!

unfortunately VCM is no good for such type of scenes

Yes you're right its too much time with too much noise sadely, the progressive mode have a lot of fireflies in this scene and bidir is worst

i think i'll wait for the next alpha/beta release with hope, i'm tired with this scene lol

yeah but the light is reacting good with vcm here, but in another scene of a simple glass cup( i'm working on it ), the light with progressive mode is better than vcm and bidir :S

i want to send you the scene but it's a 700mb size file :s will try to delete some models inside.

I could actually use some scenes where VCM/bidir fails. We are currently trying to improve it in our project. If you have any nice scene where it/path tracing does not work, send it to me. They only cannot contain much fakes.

Back to test this scene with a work around ( thanks to timko ) and it seems that the fireflies are gone with Pt-Pt progressive using  the latest legacy nightly build.

instead of using environment slot i did use a hemisphere mapped with an hdri ( the old way )

But it takes a lot of time to render it for an exterior scene, maybe because of these many proxies...

Here is the result of 6 hours of rendering and  still noisy but no fireflies i guess :

Its still quite a lot of time. Maybe one thing you can try is to use only HDR in env. slot and corona lights (hide no materials with emission enabled in scene).

i will disable the emission in the outdoor spheres and see the result.

Did you try setup with very high values for light sample multiplier?? I'd try with 16 samples for PT and 32 for lights seeing this result..

[Ludvik Koutny]

Could you just for fun try to set light samples multiplier to 0, and then also try to set light solver to simple? Just for fun :)

light samples is set to 6 lacilaci, i will test with higher values

will do with different values.

"for fun"?

is that related to my penguin render?

it's not "fun" to see such bug you know... thank you for your help anyway

Changing these things will alter the way lights are sampled. By "for fun" i mean that i do not believe it will make much of a difference, but that it's still at least worth trying, because even if it doesn't do much good, behavior of Corona after these changes could at least point us to the direction where the bug comes from ;)

i do my best to help here with my tests so we all can figure out where it did come from, timko do also work on it, we all here doing this,  i'm not here "just for fun" ;)

Ok, to explain once again. Phrase "for fun" was not related to you personally in any way. What i meant by it is that it was not an official advice, it was just a simple test to see what happens, not a verified solution. That's what i meant by "for fun" :)

ok no problem bro I'm sorry if i misunderstand you :)

since something wrong with this scene i will optimize the size so i can upload it to you guys to test.
