Title: Corona Mapping Randomizer slowdown
Post by: hrvojezg00 on 2024-07-16, 09:25:27

We`ve experienced some slowdowns in rendering, I believe, since C9 and never got to figure out what seemed to cause that, but the latest tests show it`s the Corona Mapping Randomizer. I believe there was a bug before with the UVW randomizer; it seems it shows up again. I`m uploading an interactive render test of a simple scene, with and without the Corona Mapping Randomizer applied to the wood texture. With it applied, rays are down by 50%. Do you have any insight on this?

Make sure that high quality blending is turned OFF, unless you absolutely need it. It's known to be real performance killer in mapping randomizer.

Thanks, this worked! Any other modifiers that are problematic like this one?
