172 Chapter 17: Rendering
50, when you close the Render Scene dialog (or
render), the camera Lens spinner has changed to
59.722, but the scene st ill looks the same in the
viewport and the rendering. If you use one of the
preset formats rather than Custom, the aper ture
width is determined by the format, and this control
is replaced by a text display.
Options group
Atmospherics—Renders any applied atmospheric
effects, such as volume fog, when turned on.
Render Hidden G eometr y — Renders all geometric
objects in the scene, even if they are hidden.
Effects—Renders any applied rendering effects,
such as Blur, when turned on.
Ar ea/Linear Lights a s Point Lights —Renders all area
or linear lights as if they were point lights, speeding
up rendering time.
Displa cement—Renders any applied displacement
mapping.
Force 2-S ided—2-sided rendering (page 3–901)
renders both sides of all faces. Usually, you’ll want
to keep this option off to speed rendering t ime.
You might want to turn it on if you need to render
the inside as well as the outside of objects, or if
you’ve imported complex geometry in which the
face normals are not properly unified. Default=off.
Video Color Check—Checks for pixel colors that are
beyond the safe NTSC (page 3–980) or PAL (page
3–988) threshold and flags them or modifies them
to acceptable values.
By default, "unsafe" colors render as black pixels.
You can change the color check display by using
the Rendering panel (page 3–826) of the Preference
Settings dialog (page 3–815).
Tip: This is useful for draft renderings, as point
lights render much faster than area lights.
Note: Scenes with radiosity (page 3–51) are not
affected by this togg le, as area lig hts do not have a
significanteffectontheperformanceofaradiosity
solution.
Super B lack—Super Black rendering (page 3–1018)
limits the darkness of rendered geometry for video
compositing.
Tip: Leave this off unless you ’re sure you need it.
Advanced Lighting group
Use Advanced Lighting—When on, the software
incorporates a radiosity solution (page 3–51) or
light tracing (page 3–44) in the rendering .
Compute Advanced Lighting When Required—When
on, 3ds Max computes radiosity when required on
a per-frame basis.
Normally , when rendering a series of frames,

Render Output group
Save File—Saves the rendered panorama to disk.
This is unavailable until you have defined a f ile
name by clicking the Files button.
Files—Lets you specify the name, lo cation, and file
type for the rendered panorama file.
Render ed Fra me W indow—Enablesordisablesthe
panorama exporter’s rendering display.
Display V iewer—When on, the Panorama Exporter
viewer (page 3–173) opens upon rendering the
panoramic rendering.
Viewport—Chooses the camera viewport to render.
When you render a panorama, this drop-down list
shows only the cameras in the scene.
