Accessing mental ray materials and shaders
With the mental ray (or Quicksilver) renderer selected, all non–mental ray materials include an additional
rollout labeled mental ray Connection. This rollout, shown in Figure 30.8, is available only if the mental ray
extensions are enabled in the mental ray panel of the Preference Settings dialog box. They let you override
the existing shaders used by the Scanline renderer and enable additional shaders that the mental ray ren-
derer will use.
FIGURE 30.8 Chapter 30: Using Specialized Material Types
The mental ray Connection rollout in the Material Editor lets you override the default shaders.

The lock icons to the right of the shader buttons are the default shaders used by the Scanline renderer. To
select a new shader, simply unlock these shaders by clicking the lock button. If a material is opaque, you
can speed up the rendering process by flagging the material as Opaque, using the option at the bottom of
the rollout.
If you want to get direct access to the shaders used by mental ray, use the mental ray material type, which
presents all the shaders listed in the mental ray Connection rollout.

Using the Autodesk Material Library and the Arch & Design
materials

The Autodesk Material Library and the Arch & Design materials are a set of advanced mental ray materials
designed for architects to add to buildings and surfaces found in architecture renderings. All of these mate-
rials are based on physical properties that are typically found in environments lighted with global illumina-
tion. For example, the Satin Varnished Wood template includes slightly blurred reflections and a high
glossiness to give it a realistic look.
The materials contained in the Autodesk Material Library are categorized into groups and subgroups. Each
material has several parameters allowing you to change the color, glossiness, reflectivity, and so on. The
available parameters change based on the selected material.
Many of the Arch & Design materials are already defined and available in the Templates rollout. The avail-
able presets include Pearl Finish, Satin Varnished Wood, Glazed Ceramic, Glossy Plastic, Masonry, Leather,
Frosted Glass, Translucent Plastic Film, Brushed Metal, and Patterned Copper.
