Hi,
I need to reduce the noise(in the reflections): The glass-object is simple ‘one-sided’ geo and ‘thin’.(plse find mat-editor/screen attached)
The rendersettings are 1: render time=10 min , Pass limit 60 and Light samples multiplier cranked up to 8. All other settings should be default.
2 Lights setup: bluish coronalight left and coronasun from the right. Scene env is ‘use’ Corona with a 180,180,180 RGB setting.
Any ideas which settings I could use to decrease the noise? Pls note that this will be used in animation- so rendertime will be crucial.
Simply cranking settings up is no option.
thanks Martin
-remove the falloff map from opacity - it makes no sense to use it if you are using refraction
-reset render settings to defaults
-use path tracing as both secondary and primary solvers
-why did you increase light samples multiplier to such crazy value? is there any reason for this? leave it at default 2 or even reduce it to 1
-if you want better time/quality ratio for glossy reflections - increase “gi vs aa balance” (not too much, check values like 16, 24, 32…)
-why are you using both time and pass limit? again, is there any reason? I think you should use one or another, preferably pass limit only, to have the same image quality across all of the frames
thanks for the quick response: -remove the falloff map from opacity - it makes no sense to use it if you are using refraction
It is hack, yes.But I have forgotten to mention that we are using Corona in an unusual environment: it is about cartoon characters. So it doesn’t have to be physical correct.
In this case the prop is rendered against a bended grey background waiting for approval. The refraction gives it a black ‘outline’ which is killed by the falloff.
I removed it- rendertime decreases only 2 seconds. Noise seems to be comparable.

ok…For other reasons not an option(but only very little difference)

this was due to try&error:I increased GI-AA up to 64 with little difference. cranking the multiplier up to 8 however reduced the noise. rendertime increased from somewhat 5 to 8

I’m sorry, that this was misunderstandable: I use pass limit only. But because of the huge amounts of frames that have to be rendered, rendertime per frame is crucial.
–reset render settings to defaults
this was the key! it rendered much better. I wondered why because basically I only changed the multiplier. It seems that the reason for the noise is the ‘use’ Corona env 180,180,180 RGB setting.
Can you shed some lights on this?
—it seems that is has nothing do with corona or max env: it is only the bright color which is causing the noise.
