Cycles is amazing, but getting rid of the noise or 'fireflies' in the renders can sometimes be tricky. Gleb Alexandrov shows us how to use the compositor to clean up your images.

The eternal struggle between artist and render engine is finding the balance between noise and render time. This is certainly true for Blender’s Cycles engine. Wouldn’t it be nice if we could clean that pesky noise in after the fact with the Compositor? Yes. And we can!
In this quick tip, Gleb walks us through the process of rendering with low samples, separating the image into passes, and putting it back together in compositing with significant noise reduction. This can be easily setup thanks to the bºwide Node Pack which includes a pre-made “PassCombineDenoiser” node group.
