so the check box also affects all instances of and
references to the shape.
Inherit V isibility—Causes the object to inherit
a percentage of the visibility of its parent (as
determined by the p arent’s Visibilit y t rack in Track
View). When a group parent is assigned a visibility
track, Inherit Visibility is automatically turned on
for a ll children in the group. The children will have
the m aximum visibility of the parent. Transparent
materials and hidden objects have no effect on this
function.
V isible to Camera—When on, the object is visible
to cameras in the scene. When off, cameras do
not view this object; however, its shadows and
reflections are rendered. Default=on.
V isible to R eflection/R efraction—When on, the
object has “secondary” visibility: it appears in
rendered reflections and refract ions. When off,
the object does not appear in rendered reflections
or refractions. Default=on.
Note: An object can have Visible To Camera on but
V isible To Reflection/Refraction off, in which case
the object renders in the scene but does not appear
in reflections or refractions.
Receive Shadows—When on, the object can receive
shadows. Default=on.
The mental ray renderer supports the Receive
Shadows toggle.
Cast Shadows—When on, the object can cast
shadows. Default=on.
Apply Atmospher ics—When on, atmospheric
effects are applied to the object. When off,
atmospheric effects do not change the rendered
appearance of this object. Default=on.
R end er O ccluded Objects —Allows special effects
to affect objects in the scene that are occluded by
this object. The special effects, typically applied
by plug-ins (page 3–995) such as Glow (page
3–226),useG-buffer (page 3–946) layers to access
occludedobjects.Turningonthiscontrolmakes
the object transparent for the purposes of special
effects. This makes no difference when you render
to most image files. When you render to either
the RL A (page 3–630) or RPF (page 3–631) file
format, however, occluded objects appear with the
effect applied on their designated G-buffer layer.
Default=off.
G-Buffer group
Allows you to tag an object as a t arget for a render
effect (page 3–218) based on the G-buffer (page
3–946) channel. Assigning the object a nonzero ID
creates a G -buffer channel that can be ass o ciated
w ith a render effect.
Wa rn in g : The mental ray renderer (page 3–78) does not
recognize Z-depth with G-buffers. G-buffer data is saved
on a single layer. Also, the mental ray renderer does not
support the following effects:
• Glow lens effect (page 3–226) (rendering effect)
• Ring lens effect (page 3–230) (renderi ng effect )
• Lens effects Focus filter (page 3–362) (Video
Post)
Object Channel—Setting this spinner to a nonzero
number means that the object will receive the
rendering effects associated with that channel in
Render Effects and the pos t-processing effect s
associated with that channel in Video Post.
To save the channel data with the rendering ,
render to either the RLA (page 3–630) or RPF
(page 3–631) fi le format.
Motion Blur group
By Object/By Layer—To g g l es b e t w e e n obj e c t
settings or object layer settings. Object settings
affect only the object or objects selected. Object
layer settings affect all objects on the same layer as
the selected object.
