Grainy renders (iray)

daancouzijn

Hello.

I'm trying to render a still image in the biggest size possible as I need to print it on a huge canvas. I can't get the grain out of the eyes. I already maxed out the samples and max time. See the difference on the images below. The first one (without grain) is a much smaller size with lower samples. How can I get the same effect with a bigger size?

Thanks in advance!

You can do a spot render of just the eyes with the spot render tool, and then merge both in postwork.

Also, do you know how many pixels per side you really get printed on that big canvas? Chances are, you don't need as huge a size as you think.

With "maxed out to smaples" do you mean you set "Rendering Quality Enable" to off and set Max Samples to 15000?
If not you might want to do that, or even higher by clicking on the Gear > Parameter Settings > Uncheck Use Limits
