What still causes splotches

[Crayox13]

Hi guys,
I actually bought SolidRocks because I got tired of getting into fine tuning on some of my scenes. Usually the default setup works but on some scenes, even SR can't help me. Like attached. It's actually render with a "very good" SR preset and still tons of splotches on the inner part of the room. I tried deleting objects from sofas to objects on shelves but no good. Any ideas? At the end I rendered it with Brute force which was perfectly clean.

Also, how come vraylight materials on object cause many splotches, should I adjust something if I use them? I don't use direct illumination on them.

That noise is caused by the irradiance map. Read up on how to fine tune it.

Heya

If vray materials give you splotches(I guess in refection/refraction) then you should disable interporation on them.

As to GI in general... with GI its a balance between sharp detailed blotchy map and a blurry smoth non-blotchy map. So you have to find compromise in it. Maybe more interporation samples will help clean up things.

I tend to generate reasonably blurry map from IRR/LC so its nice and smooth and then using Detail Enchance in IRR map to fix corners and detailed parts of image...

Thanks, bye.

Cool will try that. I always think my splotches are some kind of error since I don't have them on other scenes with the same settings. And this time I even let SR set it up and still splotches.

Don't use SR if you don't know what it's doing.
