Because we're using a decay filter and we're rendering light group AOVs, we need to render on the CPU instead of the GPU, and so the render device is set to CPU. We previously set four diffuse bounces and three specular bounces, and I think that's going to be fine in this case, so I'm going to leave that as it is. We'll also want to check in on our ray depth. However, I found that in my tests, using adaptive sampling actually had a problematic effect, causing more noise in the bounce light areas, so I'm going to leave the adaptive sampling off. I just want to mention in passing that there is an adaptive sampling section here, and in many cases this can be helpful to add more samples in areas of higher noise. We don't need the progressive rendering option for a production render, so we can turn that off. So that we'll get better quality in the shiny highlights, let's also increase the number of specular samples up to a value of four. Let's bring that up to a value of eight diffuse samples. We can help that by increasing the number of diffuse samples.

If we rendered our shot with these settings, we'd get a pretty grainy image, especially in the bounce light areas. For production rendering, we're going to need more samples for the diffuse and specular components. Then let's change up the Arnold settings proper, go into the Arnold renderer, and in the sampling settings, we previously set up some options here that were appropriate for a draft-quality rendering. I'll call it spot_lighting_production, and press enter. You've got a draft quality rendering listed here in our file name, so let's just change this.

In the previous chapter, we set up all of our lighting, including our light group AOVs and AOVs for the various components of the shaders, and now we're ready to render out a production-quality image, so let's set up the Arnold renderer for production quality, go into the render settings dialog, and first let's change up the file output name.
