Raytrace Extended Parameters Rollout 1361
w ith a projector lig ht. On thicker objects, you c an
get some good wax-like effects.
Fluorescence and Fluor. Bia s—Creates an effect
similar to black light on a black light poster.
The light from a black light is largely ultraviolet,
outsidethevisiblespectrum.Underblacklight,
fluorescent (page 3–1036) paints flare or glow. The
fluorescence in Raytrace material takes whatever
lightitseesinthescene,appliestheBiastoit,and
then, regardless of the color of the lights in the
scene, illuminates the fluorescent material as if it
were lit b y white light.
At 0.5, The Bias m akes Fluorescence behave just
like diffuse coloring. Bias values higher than 0.5
increase the fluorescent effect, making the objec t
brighter than other objects in the scene. Bias
values lower than 0.5 make the object dim mer
than other objects in the scene. You c an get some
chromatic shifting effects with this.
Tip: Full saturation and value for the Fluorescence
color help give the effect of commercial fluorescent
paints.

Wire group
Size—Setsthesizeofthewirein wireframe mode
(page 3–1128)
. You can set either pixels (the
default) or current units.
In—Chooses how to measure wire. With pixels,
w ires maintain the same apparent thickness
regardless of the scale of the geometry or how
near or far the object is positioned. With units,
the wires appear thinner at a distance and thicker
atcloserange,asiftheyweremodeledinthe
geometry.
Pixels—(The default.) Measures wire in pixels.
Units—Measures wire in 3ds Max units.
Advanced Transparency group
The controls in this group let you further tune
transparency effects.
Transp. ( Transparency Environment)—Similar
to the environment map in Basic Parameters,
butoverridesthescene’senvironmentmapfor
transparency (refraction) only. Transparent
objects refract this map, while reflections
still reflect the scene (or the Basic Parameters
Environment map, if one is chosen).
Click the button to choose the Transparency
Environmentmap.Usethecheckboxtotogglethe
effect of the map.
Lock button—Locks the Transparency
Environment map to the Environment map (found
on the
Basic Parameters rollout (page 2–1355) ).
When on, the Transparency Environment map
controls are disabled, and a map applied to the
Raytrace Environment applies to the Transparency
Environment as well. When off, the Transparency
Environment map controls are enabled, and the
Transparency Environment can have a different
map assigned to it. Default=on.
Changing this button’s setting here also changes it
on the
Basic Par ameters rollout (page 2–1355) and
the
Maps rollout (page 2–1364) .
Density —The density cont rols are for transparent
mate rials. If the material is opaque (the default),
they have no effect.
Co lor—Sets a transmission color based on
thickness. While filter (Transparency) color t ints
objects b ehind the transparent object, the density

within the
object itself, like tinted glass.
To use, first make sure the object is transparent.
Click the color swatch to display the Color Selector.
