The Lens Effects filters add realistic camera flares,
glows, gleams, g limmers, and depth-of-field
blurring to your scenes. Lens Effects can affect a n
entire scene or can be generated around specific
objects in your scene.
Lens Effects are applied through the Video Post
interface. To learn about adding scene and image
filter events to the video post queue, see Add Scene
Event (page 3–329),andAdd Image Filter Event
(page 3–335).

• Lens Effects Focus (page 3–362):Createsa
blur on objects based on their distance fro m
the camera. tr acks an object’s distance f rom
the c amera using a Z-Buffer. Focus uses the
Z-Buffer information from the scene to create
its blurring effects.
• Lens Effects Glow (page 3–364):Createsa
glowing light around any assigned object, such
as a laser beam or the thr uster on a space ship.
• Lens Effects Highlight (page 3–370):Createsa
bright cross star effect on a desig nated object.
Wa rn in g : When you animate Lens Effects parameters,
this creates pointers into the actual scene, so Lens Effects
animation is lost if you save the Vi deo Post queue in a
VPX file (page 3–1031). To preserve the animation, save
the Video Post data, including Lens Effects animation,
in the MAX file.
