White Dots - Fireflies?

Recommended Posts

OK I think that I have heard about this on Facebook or somewhere else but I am getting white dots in my renders using Redshift - are they called fireflies?

Whatever they are how do you get rid of them just up the sample settings?

Thanks on advance for any help 🙂

I'm only using Redshift Demo 2.61 so I can't confirm it myself, but here's a recent thread in FB:

Maybe you are using volumetric and automatic sampling

Saul Espinosa: 



You mean automatic sampling right 😉 , not super sampling.

Indeed there is a problem with the algorithm where it is generating hot fireflies in VDB volumes, I reported that a few days after the release. Rob mentioned that it is a problem and he will be addressing it when they do a second pass of the auto sampling algorithm.

But first he has to finish the shader core re-write as it will also influence how the automatic sampler works.

  • I am using Unified Sampling set to Min 16 and Max 128. No GI and no volumetrics - I am still a bit of rookie with Redshift… I think I will ask on the Redshift forums but I cannot show any renders due to NDAs.
