Graininess Around Sunglasses

Hi,

I rendered this in iray and am wondering if anyone has any suggestions for how to eliminate the graininess around the sunglasses.  Is there an iray tutorial anywhere?  Thank you.

    Let it render longer.

    If this is the result of rendering to completion (100%), then increase Rendering Quality, which can be found under Render Settings -> Progressive Render Settings

    If this isn't the result of rendering to completion (100%), increase max time, which also can be found under Render Settings -> Progressive Render Settings

    You don't have to render the entire thing again, you can just render that one spot and merge the result afterwards in a graphics editor (such as Photoshop or GIMP). Go to Window -> Panes (Tabs) -> Tool Settings. Select the Spot Render Tool and select New Window. Now use the mouse to select only the problematic area. DAZ will now render only that one spot.

    You could also denoise the render afterwards, which is usually very fast!

    The attached image is postprocessed using the Intel Denoiser described in this thread:

    Hi. That is a very interesting looking script you have put together.  I will look into trying it another day when I have more time.  Thank you.
