Grainy render in Redshift

Recommended Posts

I am experiencing a fair amount of grain in a Redshift render. When working with Physical render, all controls that affect the quality are found in 1 place + GI. With Standard render, the options are set in the materials. Which approach does Redshift take? I found the override options in Basic tag and some in the material, but none for the Shadows quality.

The main quality settings for RS are under the Basic tab under Unified Sampling.  The default settings are VERY low, so don't be afraid to crank those up.  The rule of thumb is to double the number each time you increase it.  I think RS likes even numbers, but I just heard that somewhere so I don't really know if it makes a difference.  If you're using GI and/or have some moderately complex stuff going on in your scene, don't be surprised if your Samples Max is over 1000.

 

Here's a good tutorial to get you started:
