I am using Iray (Full HD 16:9) and I keep getting pixelated and/or white areas of graininess. What is the best setting to adust to get rid of these and get better image quality?

    What are your render settings, and can you please post an image of them, and what you are seeing?

    Generally when you get a pixeleated image, it is because either there is not enough light, or you have not let the image render long enough.   There are some useful threads on Iray here: http://www.daz3d.com/forums/discussion/56788/iray-start-here#latest

    Since I'm still learning this, the only thing I change from default is "Ground shadow intensity" and "SS time." Light source, if I use one, is commonly basic light or sun light. The white spots on the skin on the right and the majority of the grey on the left might clear up a little bit more, but looks mostly like this in the end.

    When you say "basic light"... what does that mean?

    Have you turned off the headlamp?

     

    There's a few things causing this, probably.  The surfaces are highly reflective (using 255,255,255 white somewhere in specular) and the scene itself is very bright. Those are what are reffered to as "fireflies", though you will see the term incorrectly applied quite frequently.  Fireflies, in my understanding, are hotspots...that are taking a longer time than the rest to resolve.
