Hi,

I am having problems with Iray. I have rendered a scene with 200 iterations using the De-Noise filter. Also, I have activated the "Elminate shadow artifacts" option. I always get white dots in some places of my final image. You can see this effect on the shirt of my character.



With 1000-1500 iterations, I can reduce almost all the dots, but the rendering time is too long. I think that I must be making some kind of mistake. Could you please help me?

Thank you.

They are not only on the shirt. If you look closely, they are all over the place.
Wait until the next Iray update. Hopefully there would be introduction of better Firefly filter handling.
For now it can be fixed manually: https://forum.reallusion.com/FindPost403778.aspx

Another example. Two images rendered with 200 samples and denoiser

Ok! I didn't noticed that there was another topic about this problem.

Thank you for your help, 4u2ges.
