Lens Effects Parameters rollout
The L ens Effects system allows you to apply effects
to your rendered image by choosing a particular
effect from the list on the left and adding it to the
list on the right. Each effect has its ow n rollout
of parameters, but all effects share two panels of
global parameters.
Lens Effec ts G lobals rollo ut, Parameters panel
Loa d—Displays the Load Lens Effec ts file dialog
that enables you to open an LZV file. The LZV
file format contains information saved from a
prev ious configuration of Lens Effects. This allows
you to load and use Lens Effects that have been
saved from previous sessions of the software.
Save—DisplaystheSaveLensEffectsfiledialog
that enables you to save a n LZV file. The LZV file
format contains information saved from a previous
configurationofLensEffects.Thisallowsyouto
save several typ es of Lens Effects and use them in
multiple 3ds Max scenes.
Note: Saving an effect as an LZV fi le will only save
the attributes of the effect on the frame that it is
saved at. The LZV file format doesn’t save the
animation keys of an animated p arameter.
Size—Affects the size of the overall Lens Effect.
This value is a percentage of the size of the
rendered frame.
Intensity—Controls the overall brightness and
opacity of the Lens Effect. Higher values produce
a bright, more opaque effect, and lower values
produces a dim, transparent effect.
Seed—Gives the random number generator in
LensEffectsadifferentstartingpoint,which
creates a slightly different Lens Effect w ithout
changing any settings. Us ing S eed guarantees a
different Lens Effect, even if the differences are
very small. For example, if you set up a Ray effect,
you will get slightly different r ays in the lens flare if
you adjust the seed value.
Angle—Affects the amount that the Lens Effect
rotates from its default position, as the position of
the effect changes relative to the camera.
Sq ueeze—Squeezes the size of the overall
LensEffect,eitherhorizontallyorverticallyto
comp ensate for different frame aspect ratios.
Positive values stretch the effect horizontally, and
negative values stretch it vertically. The va lue is
a percentage of the size of the flare. Range=100
to -100.
Lights group
Allows you to choose lights to apply Lens Effects to.
Pick Light—Enables you to select a light directly
through the viewpor ts. You can also select a lig ht
by pressing H to display the
Select Objects dialog
(page 1–78)
.
Remove Light—Removes a selected light.
