Exclude from Adv. Lighting Calculations—When
on, the current selection is excluded from
advanced lighting ( radiosity or light traci ng).

contribute to indirect illumination.
By Object/By Layer—Toggles between object
settings and 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. Most settings on this rollout
are available only when this toggle is set to By
Object. Default=By Object.
Note: If multiple objects with different settings are
selected, this button will read “Mixed.”
Adv. Lighting General Proper tie s group
Cast Shadows—Determines whether objects will
cast shadows in the radiosity solution.
Note: When disabling Cast Shadows, you should
also turn off
Diffuse (reflective & tr a nslucent)
and Specular (transparent) in the R adiosit y-only
Properties g roup. If these sw itches are left turned
on, objects will still generate light that can produce
artifacts in the solution.
Receive I llumination—Determines w hether objects
will receive indirect ill umination.
Num. Regathering R ay s M ultiplier— Lets you
adjust the number of rays cast by this object, per
pixel. If an object looks “blotchy” after rendering,
Increasing this value can improve its appearance.
Default=1.0.
Tip: Increasing t his setting is most useful for
objects with large, smooth surfaces. Mor e complex
geometry tends not to show advanced lighting

Radiosit y-o nly Properties group
Diffuse (reflective & tra nslucent)—When on, the
radiosity s olution will process diff use reflection
and
translucency (page 3–1121) of the selected
objects.
Specular (transparent)—When on, radiosity will
process transparency of the selected objects.
Exclude fr om R egather i ng—When on, objects
are excluded from the regathering process when
rendering.
