Artifact fuzz in renders

Ben Oaks

This is definitely a newbie inquiry. I apologize in advance if I have missed the topic that addresses this issue. 

 

When a render is completed upon inspection I have noticed that there are "spots" within it that resemble dust particles. Little white spots or snow-ish particles. I have the render settings set to normal now, but I have tried multiple settings to try and fix this. My question is if this is normal? Or is it a hardware issue on my end? I use an nVidia 1050 Ti for my renders.Here is the latest example I rendered last night. plus a zoomed in cut so it may be more visible.

Your scene is very dark. Iray needs a fair bit of light to converge and eliminate noise. You need more light or more render time or both. When you say "Render settings set to normal", i don't know what you mean. There is no "Normal" tab for Iray. If youmean default, then you are probably rendering long enough, but need more light.

The default settings for Iray spotlights (1500 Lumens) are way to small. You should genreally be using values >100000.

If want a darker scene, use the tonemapping  options to reduce exposure to taste.

Thank you for the quick response. I will take lighting into consideration. Will be rendering the same scene with more lighting options tonight, and will post the results. Thanks again.

Yes by normal I meant Default.

@Ben Oaks

What lighting do you have in the scene? If you can show me what lighting/values are in the scene, I can probably help you get close to what you want with less frustration. 

Feel free to take a look at my gallery for some examples. https://www.daz3d.com/gallery/users/5891
