Hey, Sozap!
First of all, thank you for such an extensive answer. Finally I realized what’s renders/viewports values is about. Believe or not, but I couldn’t find the answer whether I’ve been searching on YouTube or just surfing the internet. Thanks once again!
Yeah, I know that without activating denoising feature, the final render looks noisy, but, in some cases, sometimes I decide to left a bit noise just because it’s fits to the scene. By the way, in this my work I have cleaned the noise, but here you can see the variant with it (you may see it if you look closely at the snow), which is, in my opinion, looks better:
Thanks, have a good day!
