General Panel (Object Properties Dialog) 117
For shapes, the Renderable check box in the
Object Prop erties dialog affects the main object,
so the check box also affects all instances of and
references to the shape.
Inherit V isibility—Causes the object to inherit
a percent age of the visibilit y of its parent (as
determined by the parent’s Visibility track in Track
View). When a group parent is assigned a visibility
track, Inherit Visibility is automatically turned on
for all children in the g roup. The children will have
the maximum 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 v iew 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 refractions. 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 Occluded Ob j ects —Allows special effects
to affect objects in the scene that are occluded by
this object. The speci al effec ts, typically applied
by
plug-ins (page 3–1089) such as Glow (page
3–222)
,use G-buffer (page 3–1040) layers to
access occluded objects. Turning on this control
makes 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
RLA (p age 3–680) or RPF (page 3–681)
file format, however, o ccluded objects appear with
the effect applied on their designated G-buffe r
layer. Default=off.
G-Buffer group
Allows you to t ag an object as a target for a
render effect (p age 3–214) based on the G-buffer
(page 3–1040)
channel. Assigning the object a
nonzero ID creates a G-buffer channel that can b e
associated with a render effect.
Wa rni ng: The mental ray renderer (page 3–77) 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 3–222) (rendering effec t )
•
Ring lens effect (page 3–226) (rendering effect)
•
Lens effects Focus filter (page 3–377) (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 post-processi ng effects
associated with that channel in Video Post.
To save the channel data with the rendering,
render to either the
RLA (page 3–680) or RPF
(page 3–681)
file format.
Motion Blur group
By Object/By Layer—Tog g l e s 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 selec ted object.
