Raytrace Motion Blur 

This attribute enables

Enables or disables motion blur for traced rays. For example, a moving object as seen in a mirror will only show motion blur if this option is enabled.

Raytrace Displacements

When this attribute is checked, it enables

Enables or disables ray tracing of true geometric displacements. The default is to ray

-

trace displacements as bump maps (a displaced surface appears bump mapped in a mirror reflection). Enabling this feature makes ray tracing slower and

forces 3delight to

forces 3Delight to use more memory so this option should be used with care.

Raytrace Bias

Specifies a bias for rays starting point to avoid potentially erroneous

intersec- tions

intersections with emitting surface. The default value is ‘0.01’.

Trace subset

This attribute is used to select

Specifies one or several Maya object sets that is used to narrow down what objects are visible to ray traced rays. This feature can be useful when a scene is using referenced objects that already have their "

Trans- mission

Transmission" attribute correctly set, but only part of these objects are needed to be visible to ray traced rays in this specific scene.

The "Trace subset" option menu has the following values available:

Info

Note that the 3Delight for Maya built-in Hypershade shaders will ignore the trace subset attribute when computing reflections and refractions. Only the Visible in Reflections and Visible in Refractions render stats attributes will be honoured for reflections and refractions.
