Title: Noise level
Post by: Relight on 2019-12-12, 12:50:53
Hi,
I'll suggest in next version to add a command to tell to the render engine to calculate the noise level not taking in account the background, so looking only for the geometry.
I.e. rendering an external view of a building, there is a great area of the image occupied by the sky, taking into account the whole image the noise level is very low for the sky but high on the building, so the mean value is low and the render stops.
There is the option to use passes limit, but I can't know how much passes are enough to clean the image and noise limiter is esasier.

Moving this to feature request board, as it has little to do with bug reporting.

Good idea !
I also suggested to calculate more intense in the areas of shadows, because lighter areas clean up quicker.
Already posted this month ago.

Maybe Corona devs will succeed to implement it. Would save tons of time.

I suppose this falls into a general "improve how noise limit works" request.

About this:

Currently less samples are devoted to shadowed areas and this is actually intentional. I do not remember why exactly it was changed, but I think it was related to the shadowcatcher material.

We will definitely look into both issues.
