Damn_daniel Posted March 22, 2020 Share Posted March 22, 2020 Hi guys, I'm pretty new using Redshift as an render engine and I have a problem that I know how to solve. I've created a large column of red smoke, but when I render it always appears an annoying shiny noise. I've tried to increasing samples of all the lights to 8192, the gi sample have the same value and I've also override the volume samples to 16384. The uniform samples are: min samples 16 and max samples 128. What can I do to clean up the render? I've tried to increasing the uniform samples but doesn't seem to show any change and increase the render time a lot. I've attached and image to show you this shiny noise on the volume. Thank u in advance! Quote Link to comment Share on other sites More sharing options...
p2or Posted March 24, 2020 Share Posted March 24, 2020 Hi @Damn_daniel. At a first glance looks like fireflies to me. If you have access to Nuke, there is a great gizmo: http://muellerstefan.de/?p=20. Do you mind sharing the file so we can have a look?

Atom Posted March 24, 2020 Share Posted March 24, 2020 If you're using a dome light, try blurring the source image. Sometimes an HDRi can contribute to noise in a render. Quote Link to comment Share on other sites More sharing options...
