Increasing Skydome render sampling

- [Instructor] When the render completes…in the Arnold render view,…we can see that it's very grainy.…The lighting is what we want,…but the sampling is nowhere near high enough quality.…Let's open up the render settings.…In the Arnold renderer tab, we have the sampling section.…I've already set the ray depth.…Let's open that up and take a look.…I've got five diffuse rays…to provide sufficient bounce light,…four specular rays to prevent any black areas…on shiny surfaces near one another,…and transmission set to eight by default…to permit rays to travel through transmissive materials.…

Up in the sampling, let's start increasing these values.…Bring the camera rays up to seven…and that's going to drastically increase…the number of samples here.…If we set the camera rays back to three,…which is the default,…we see we have a minimum of 117 and a maximum of 243.…If we increase the camera anti-aliasing to seven,…now our maximum is 1323,…so it's jumped up quite a lot.…

We can also increase the rest of these individually.…
