Holy crap, this new adaptive sample is blowing the previous one out of the water. I have only done one test on a small image for now, but the results are night and day. In the example 10 minute render below, v5 got to 8.46% noise level. the v6 daily got down to 0.43% noise level! FYI, the black areas are a hold out I setup to speed up rendering.

Also not to mention the speed ups in the geometry stage. This is insane, my renders are going to be so much damn faster. I am very impressed.

Njen, your results are puzzling me - noise level reports insane improvement, but visually V6 looks even noisier than V5

Yeah, I'm now finding that my earlier excitement is probably overstated too much. I mean, I think it is an improvement, just not to the extent I was reacting to before.

In the images below, the first image is a previous frame I rendered on one of my Threadrippers. I then rendered the same frame on my workstation (my render boxes are tied up currently). I still see a fair amount of noise in the new adaptive sampler. Is noise being calculated differently now?

I should have put this info in the images:
01 - v5
02 and 03 - v6 daily

Hi all,
this is my first comparison in scene with hdr as exterior light and interior lights.
10 mitutes times calculation.

The new solver has less noise but seem to lose reflection in material and givre brownish color.
I prefer the old solver in that case.

It is possible that noise level is just calculated differently in v5 and v6.

@LorenzoS, does your old scene has portals? In previous versions Corona has a "bug" where sometime portals were significantly changing scene lighting. See my old topic on this: https://forum.corona-renderer.com/index.php?topic=26466.0 This was fixed in the latest build, so it could be this. AFAIK if you compare the same scene rendered in V5 without portals and in V6 without portals, they should be virtually identical, appart from the noise level. If that's not the case, i suggest to provide the scene to the support team for investigation.

hi romulus,
no portals on my scene.
I did the test with Corona version: 6 (DailyBuild Feb 20 2020) for both images.
I did "new_solver.jpg" using "adaptive sampler" on system setting.
I did "old_solver.jpg" using "NormalDep Compensated" on system setting.

But i don't know if this is the correct approach.

According to maru, your approach is correct. If the only thing that you've changed, was enviroment solver, then i don't think that such difference is considered normal. Let's wait and see if support team will want the scene for investigation.

While the devs are looking at the new environment sampler can they please take a look at getting environment overrides working properly? The current implementation is unusable with HDRI's which produce insane amounts of fireflies and involves tedious workarounds.
Vray who?

While I can not show my example, but I must say am impressed by the new sampler and how it cleans the interior faster. Well done!

Hi Lorenzo,

This is the correct approach. Please would you be able to share your scene with us? We can look into the issue with reflections.

Hi rowmanns,
ok i will share the scene, only for staff i recommend.

looking better i think it's not only a iussue with reflection but a iussue with light calculation (see the upper left area on the wall, the shadow/light in the new solver image is lost).

Please can yuo give the link for upload?

thanks
