We will need to adjust the Diffuse and Glossy attributes in order to get a believable brushed metal effect. Due to a large number of controls, the Standard shader is split up into several groups such as Diffuse, Specular, Sub-Surface scattering etc.
The Standard Surface shader is very powerful, and allows a large number of different sorts of materials to be created, but can be somewhat daunting at first. The Standard Surface shader is a multi-purpose shader capable of producing all types of materials, from simple plastic to car paint or skin. We will use the Standard Surface shader to shade the robot and give it a metallic finish. If you select a light and then inspect the Maya attribute editor, as well as the regular light attributes, you will also see a new group of Arnold attributes for the light, which is where any additional settings used by Arnold can be accessed. As well as using Arnold's lights, you can also use standard Maya lights when rendering with Arnold. We will use Arnold's own proprietary lights to achieve a physically accurate, photo-realistic lighting setup. We will go through the steps of lighting, shading and rendering a toy robot model using the Arnold renderer. In this tutorial, we will cover how to build a simple photographic lighting studio setup that can be used for lighting and rendering all manner of objects. This is a beginners tutorial that introduces MtoA, a plug-in which allows you to use the Arnold renderer directly in Autodesk Maya. Arnold is an advanced Monte Carlo ray tracing renderer built for the demands of feature-length animation and visual effects movies.
