Problem:Yesterday I was doing an image with quit dense clouds in it, this naturally meant that an increase in cloud, shadow and atmosphere samples via their respective dialogs; I tried 64 and 164 as recommended on the forums the image was unacceptably noisy I tried again at 204 still far too noisy then I ramped it up to 402 and after 11 hours of rendering and waiting till two in the morning I had to kill then render, as sleep was more important.
The area's that noise are found in are mainly in shadows and cloud bases, the only place you can increase shadow samples is in soft shadows there is no place of standard shadows both on terrain and clouds.
Request:A brush based way of adding samples to problem areas on an image on a local rather than global scale; for example if an increase in the cloud quality tab fails for a given area you be able to use the sample brush to go in and fix it, rather than trying to through more samples via the global quality setting in the quality tab.
Surely for any artist there must come a point, where the exponential wait time form high and higher sample increase to deal with an exceptionally noisy image when short of having a render farm at home (Expensive and hardly practical) is beyond the pale, in other words money for old rope.
A brush based system for applying samples to areas that are problematic would only increase sample density to the areas required and would save render time for both Independent artists such my self, to large studios on tight deadlines.
I realize that such a thing may take time, but maybe worth at least looking into.
