Figure 6.36 - Render settings
One of the biggest challenges to render a scene in Cycles is finding an
optimal sample limit that will give you a noiseless image. Usually, a
value between 500 and 1000 gives you good results, but it depends on
several factors. The difference in render times from 500 to 1000 samples
could be a few minutes or hours.
To help you using fewer samples for a faster render, we can enable the
Denoiser tool in Cycles. Go to the Sampling options and enable the
Denoiser tool. Below your Sampling settings, you can enable the
Denoiser for either the render or Viewport. The Viewport option removes
noise from a render preview (Figure 6.37).
