Issues with graininess and noise in KeyShot

Environment Details

• KeyShot
  • Any version 

Resolution 

1. Open the render window
2. Go to the Options tab
3. Under Quality, select Custom Control
4. Increase the Shadow value to a number between 2 and 3, say 2.5.*
5. Set the Samples value to 32 and a test image at low resolution, say 800x800. You can also render a region.
6. If your low-resolution image looks good, then you can render the full-size image with the current settings. Otherwise, double the Samples value and run another test.
7. Keep doubling the Samples value until you achieve the desired output.

*Higher Shadow values will lead to longer render times.
