Rendering in High Resolution for good Denoising

Post by johannes.wilde » Thu Feb 18, 2021 10:12 am

After some tests with different render sizes and settings, amount of samples etc. i am really impressed with the low amount of samples you can get away with, if you have enough pixels to work with for the Denoiser.

I rendered the image in 5760x3240 with the lowest amount of samples(32) for Cache Friendly Rendering.

Then i did some slight post production in RawTherapee and scaled the image down to 4k resolution.

The rendering just took me 8min 57sec on a RTX2080ti and a Ryzen 1700x
I will never again spend thousands of samples on a 1k image i think :idea:

Nice trick, there is another approach too, when I want to create a big image with good quality. first, I'll cache the light with a small size image and use that cache to render a huge size image without actually light calculation. this trick will give you better results and also it is much faster.
