Denoising an Arnold rendering

“

- [Instructor] The Arnold renderer is a brute force Monte Carlo renderer and it's main limitation is that it will output a fairly grainy image unless you employ some special techniques such as adaptive sampling or as we'll see this week, post process denoising. And there are two different ways of denoising an image in Arnold. One is designed for active shade and the other is designed for production rendering. Let's take a look. Go into the render setup dialogue, and I've got that set up for active shade mode. If we go to the Arnold Renderer tab we'll see that I've got some pretty low sample settings and I've disabled adaptive sampling. And because most of the light in this scene is indirect, we're going to get a very grainy image. But, if we go over to the denoiser tab here, we have a couple options. We'll see optics denoiser and Arnold denoiser. The Arnold denoiser is disabled for active shade mode. It will only work in a production rendering but the optics denoiser from Nvidia is…
