Adaptivity and Shadow channel

(1/3) > >>

tradstown:
I already wrote about these problems in a "The most wanted feature?" topic.
There is a problems with Focus Sampling and Shadow channel. Please, let me know, if there is some news about these problems.
I attached scene and some images of the problems here:

We already have this logged.
What you see is the effect of using the adaptive environment sampler. I do not have any explanations from the dev team yet, but I guess it makes rendering faster this way (and also makes it looks weird in the sampling focus element).
The shadows element issues look like a bug and we will look into it.

As a temporary workaround, you can try changing the adaptive environment sampler to anything else than "adaptive" in the development/experimental stuff rollout - https://coronarenderer.freshdesk.com/support/solutions/articles/12000021288

Hello Maru, thank you for reply! As all of us know, it doesn't make our renders faster on the latest passes now, as Focus of Sampling focusing on the areas, that no need to be cleaned. All of us using Denoiser to clean image in the end after 8-10 or even 20 hours of rendering using 20 cores processors. Hope it will be fixed in a near feature and Corona will become faster on the latest passes!

Or maybe it stops sampling in the places where sampling is not needed? :)

Maybe =)
Maybe it should work like this, but in of all interiors, corners staying noisy every time, while all image is already clean long time ago. Theoretically it should work like in Fstorm renderer: few hours of noisy image and after corners and other noise parts should become clean, but instead it renderin 8 hours and still noisy.
