got it.
with passes, what If I change resolution? do I have to make the tests on the exact output resolution to have consistent results?
With larger resolution you can get away with larger noise, so quite often half the passes are necessary. But it's important to not have too little passes since +/- 100 passes are requires for clean AA.
What happens when you find out you only need 50 passes to have good noise on high-res image, lower the AA/GI ratio to get 100 passes in the same time. If you're rendering frequently very high-res images, you can just make your default ratio something like 8/2 instead of default 16/2 and forget about it. It's better for IR and IR with Optix Denoiser as well since you get faster feedback.
I think I have that as default Corona settings since I don't really want to change it per project like Vray :- ).
I don't get it... can you explain better?
I mean, I always thought I had to rise up number of passes with high-res images: what do you mean with "good noise"? And what about denoise parameters in that case?
And what do you mean with high-res? 6, 9, 12K?
Thank you in advance,
