Work as physically correct as possible, I refer to materials, natural and artificial lights, the camera etc. In interior renderings it may make sense to bring it to 3000 subs, with a size of 0.01 and a retrace of 4. The light cache is very important, it is used to calculate the importance sampling, adaptive light and for the adaptive dome light. Now the irradiance map is the past, chaosgroup seems to have abandoned its development, I believe that soon they could just eliminate it as an option … My only suggestions are the usual boring ones.ĭon’t mess with the settings, unless you know exactly what you are doing, which may be your case, since you are very experienced, but remember that there are consequences … In the old days render took 8 hours without optimizations, you lost a whole day to optimize, to then have the render in 1 hour … no sense I know that time is money, but often in the past more time was lost in optimizing the scene and the subdivision of materials and lights than in designing in 3d and creating beautiful materials and atmospheres.

Judging by what I read, here and on the chaosgroup forum, I seem to notice in you and in other colleagues a certain difficulty in abandoning a workflow and a way of reasoning made of shortcuts and experience of the past, which puts the time to render to first place, which now and in general has been increasingly discouraged by chaosgroup. P.s.: The scene you’re using, it’s mine… I made that for the tutorials of v-ray 3 release Re render the scene and let me know… you should have faster render times and almost zero noise. Now there is still to understand how you lit the scene and what materials you used, because even these elements can create noise problems. Subdivisions: for interiors raise it to 2000, or even 3000 for really gi intensive scenes.Max subdivision: 100 (gpu engine works differently then the cpu one.noise limit: 0.005, I won’t go below that value, never, first try with 0.02 or 0.01 at most.Use the quality slider if you want to increase quality, but do not go over high quality.įor best quality chenge the settings below: My general advice is: neve touch the default settings unless you know what you are doing… Your set up is totally wrong for gpu rendering. These are my settings but the noise does not disappear with GPU
