Glass and refractive surfaces in Arnold

- [Instructor] Hi I'm George Maestri…and today we're going to take a look at Arnold rendering…and we're going to look at glass and refractive surfaces.…So we're going to render something…that looks a little bit like this,…which is going to be a glass sphere with some refractions…so let's go ahead and get started.…Now I'm going to start off…with this file called Refract_Start.ma…and if we jump out here,…we'll see it's a pretty simple file here.…If I go into a perspective view,…you can see it's just a sphere in front of some cylinders…on a backdrop with a camera…and this is the camera view that we'll be working with.…

Now I've already set up the lights and everything…so we can just focus on…creating a glassy refractive material.…Now if I want, I can go into my Render Settings…and make sure we're in our Arnold Renderer…and I'm actually going to turn down some of my samples here,…just so that it renders a little bit faster.…So I'm going to turn down samples on Camera (AA),…Diffuse, Glossy and Refraction.…Now this is going to give me a slightly noisy render…
