Shading preferences

In the Preferences window, the default Shading preference settings consist of the following:

Light settings
Mesh Tessellation settings
Surface settings

To access the Shading preferences:

From the MotionBuilder menu bar, select Settings > Preferences.
In the Preferences window, click the Shading preference option.
The Shading preference settings display.

Shading preferences

The Lights preference settings lets you set default preferences for Light assets. The following table describes the Lights preference settings.

Lights settings	Purpose
Use Volumic Light Optimization	The Use Volumic Light Optimization option lets you select a slower display method which is necessary for some OpenGL drivers. The default option is active.
Use Additive Specular Lighting	The Use Additive Specular Lighting option improves and saturates specular highlights if your video driver or card can support it. The majority of graphics cards support this setting. Disable this option only when using problematic video drivers or cards. When this option is disabled, the standard OpenGL lighting equation is used. The default option is active. See Specularity slider for more information.

Purpose

Use Volumic Light Optimization

The Use Volumic Light Optimization option lets you select a slower display method which is necessary for some OpenGL drivers. The default option is active.

Use Additive Specular Lighting

The Use Additive Specular Lighting option improves and saturates specular highlights if your video driver or card can support it. The majority of graphics cards support this setting. Disable this option only when using problematic video drivers or cards. When this option is disabled, the standard OpenGL lighting equation is used. The default option is active. See Specularity slider for more information.

The Mesh Tessellation preference settings lets you choose the way MotionBuilder tessellates quad to triangle strips: right or left ( |/| or |\| ). Most video drivers or cards support the conversion of quad to triangle strips. Activate these options only when using the Edge Cartoon shader when you need to match the edge of a quad perfectly.

Tip

If seams between the geometry and shader appear when you use Patches or NURBS with Edge Cartoon shader, try setting this option to Left. The default option is Right.

See Edge Cartoon shader settings for more information.

The Surfaces preference settings let you select default preferences for polygon geometry and NURBS or Patch tessellation. The following table describes the Surfaces preference settings.

Surface settings	Purpose
Use Strip For Mesh	Activate the Use Strip For Mesh option to convert polygon geometry to triangle strips to speed up display. Disable this option when using problematic or old video drivers, old video cards, or geometry with strip algorithms. The default option is active
Surfaces Optimization	The Surfaces Optimization option represents the tessellation of Patches and NURBS. This option maximizes Patch and NURBS processing speeds with no loss of quality. Activate this option to avoid having a deformed patch or NURBS evaluated at each frame. Disable this option only if activation causes problems. The default option is active.
