[Max] General Discussion / Re: Does a higher resolution image require more passes?
« on: Today at 15:05:38 »
If you are rendering in hi-res (let's say 4k or larger), you can actually bump up GIvsAA to 32 or more. This way you will get less noise from GI and when rendering in such resolutions you don't "care" about AA that much so you can render a lower number of passes.
Quick thought experiment:
- imagine rendering a tiny image like 50 px - it will probably become "noise free" very quickly (i.e. there will be no large difference between pixel colors between each next pass)
- imagine rendering a huge image like 50k px - it will require a lot of time to reach acceptable quality at 1:1 zoom, but if you zoom out, it will probably look as good as the 50px image :)
