Chapter 23: Rendering a Scene and Enabling Quicksilver

When the Quicksilver Hardware Renderer is enabled, the Renderer panel displays the options available for
this renderer, as shown in Figure 23.7. This renderer supports many of the options found in the more
advanced mental ray Renderer, including the mental ray materials and lights. If you use any hardware shad-
ers in the scene, you can specify their directory in the Hardware Shaders Cache Folder located at the bot-
tom of the panel.

Cross-Ref
You can learn more about the mental ray rendering options in Chapter 47, “Rendering with mental ray.” n

FIGURE 23.7
Many of the options for the Quicksilver Hardware Renderer are similar to the other renderers.

Rendering Preferences

In addition to the settings available in the Render Scene dialog box, the Rendering panel in the Preference
Settings dialog box includes many global rendering settings. The Preference Settings dialog box can be
opened using the Customize ➪ Preferences menu command. Figure 23.8 shows this panel.
The Video Color Check options specify how unsafe video colors are flagged or corrected. The Flag with black
option shows the unsafe colors, and the Scale Luma and Scale Saturation options correct them by scaling either
the luminance or the saturation until they are in range. You can also choose to check NTSC or PAL formats.

Caution
Be aware that the Scale options can discolor some objects. n

Output Dithering options can enable or disable dithering of colors. The options include True Color for
24-bit images and Paletted for 8-bit images.
The Field Order options let you select which field is rendered first. Some video devices use even first, and
others use odd first. Check your specific device to see which setting is correct.
The Super Black Threshold setting is the level below which black is displayed as Super Black.
The Angle Separation value sets the angle between the Hotspot and Falloff cones of a light. If the Hotspot
angle equals the Falloff angle, then alias artifacts will appear.
