I’m wondering, what should be be the LC+BF for big rendering size image bigger than 5000 px?
- Interior (may be LC+IM but preferably BF)
- Exterior

Thanks

I don’t know what you’re trying to achieve? Speed? Quality? Ease of setup? Low RAM usage? I’m using BF+BF for some 6000x4000 exteriors.

For final renders at 5k+ I just start with the default settings. So LC+BF. The only thing I change is the LC subdivs : I increase them between 2500 and 3000.
Then I only change some settings if I need a faster rendering or less noise, etc.

Thanks, I was thinking that bigger scene need lower quality due to the image size increase. I read something like that decades ago, but can’t find anymore such info.
