Their setting affects all Raytrace mat erials and
Ray trace maps in the scene, unless you set local
overrides.
Note: In versions prior to 3ds Max 5,thesecontrols
were found on the Raytracer Options dialog,
which is no longer present.
Enable Ray tracing—Turnstheraytraceronoroff.
Default=on.
Even with raytracing off, Ray trace material
and Raytrace map still reflect and refract the
environment, including both the environment
map for the scene, and the environment map
assigned to the Raytrace material.
Raytrace Atmospherics—Turns the ray t racing
of atmospheric effects on or off. Atmospheric
effectsincludefire,fog,volumelight,andsoon.
Default=on.
Enable S elf Reflect/Refract—Tur ns self
reflection/refraction on or off. Default=on.
Can an object reflect itself? For example, a teapot’s
body reflects the teapot’s handle, but a sphere will
never reflect itself. If you don’t need this effect, you
can improve render time by turning off this toggle.
Tip: If you have a transparent object such as glass,
and Enable Self Reflect/Refract is on, you don’t
have to m ake the object
2-sided (page 3–995) .The
raytracer sees back faces when exiting refractive
objects.
Reflect/Refract Material IDs—When on, the
material reflects effects assigned to material IDs in
the renderer’s
G-buffer (page 3–1040) on or off.
Default=on.
By default, Raytrace material and R aytrace map
reflect effects assigned to a material’s ID, so that
G-buffer effects are not lost. For example, if a
raytraced object reflects a lamp made to glow with
the Video Post Glow filter (Lens Effects Glow), the
reflectionglowsaswell.
Render objects inside r aytr aced obj ects—Tur ns the
rendering of objects inside raytraced objects on
or off. Default=on.
Render atmos pheri cs inside r ay tr aced
obj ects —
Turns the rendering of atmospheric
effects inside raytraced objects on or off.
At mospher ic effects include fire, fog, volume light,
and so on. Default=on.
Enable Color Density / Fog Effects—Turns the col or
density and fog features on or off.

you exclude objects from ray-tracing.
Show Progr ess Dia log—When on, rendering
displays a window with progress bars titled
Raytrace Engine Setup. Default=on.
Show Messages—When on, displays a window,
Raytrace Messages, that shows status and progress
messages from the ray trace engine. Default=off.
