Selection Information rollout
Num . G e omet ric O bjects —The number of
geometric objects present in the current select ion.
Num. Light Objects—The number of lights present
in the current selection.
Geome tric O bject Radiosity Proper ties rollout
Exclude f rom Adv. L ighting Calculations—When
on, the current selection is excluded from
advanced lighting (radiosity or light tracing).
Objectsexcludedfromadvancedlightingwillnot
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 a ll objects on the same layer a s
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 settin g s are
selected, this button will read “Mixed.”
Adv. Lighting General Propertie 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 & translucent)
and Specular (transparent) in the Radiosity-only
Properties group. If these switches are lef t tur ned
on, objects will stil l generate lig ht that can produce
artifacts in the solution.
Receive Illumination—Determines whether objects
will receive indirect illumination.
Num. Regathering R ays Multiplier— Lets you
adjust the number of rays cast by t his object, per
pixel. If an object looks “blotchy” after rendering,
Increasing this value c an improve its appearance.
Default=1.0.
Tip: Increasing this sett ing is m ost useful for
objects with large, smooth surfaces. More complex
geometry tends not to show advanced lighting
artifactsasmuchassmoothsurfacesdo.
Radiosit y-o nly Proper tie s group
Diffuse (reflective & tr anslucent)—When on, the
radiosity solution will process diffuse reflection
and translucency (page 3–1027) of the selected
objects.
Specular (transparent)—When on, radiosity will
process transparency of the selected objects.
Exclude fr om R ega ther ing—When on, objects
are excluded from the regathering process when
rendering.
