Layer Controller 325
The values in the second argument are chosen so
that as the distance decreases toward the threshold
of 35, the number of segments increases toward
MaxSegs. The addition "3+" ensures that the
cylinder always has at least three segments, even
whenthedivisionroundstozero(Segmentsisan
integer).
Note: To the expression, it doesn’t matter w hether
the camera is moving, or the cylinder, or b oth.

The Layer Controller dialog provides commands
andoptionsrelatedtotheLayercontrollersinyour
scene, which the system automatically assigns
for you w hen you enable animation layers (page
2–326) on an object.
Unlike other controllers, you cannot assign a Layer
controller explicitly to a track; you first need to
enable layers via the Animation Layers toolbar
(page 3–690) or the Controller menu of the Curve
Editor.
The Layer controller dialog has similarities to the
List controller (page 2–342) dialog. You can refer
to it for complementary informations on some of
the options.
Animation Layers and Autodesk V IZ
Although the Animation Layers feature is not
available in Autodesk VIZ, V IZ can load and save
objects that use this feature without any data loss.
The Layer controllers continue to exist in VIZ,
and can even b e viewed and edited in Tr ack View,
although editing of the animation-layer data is not
recommended if the objects are to be returned to
3ds Max.
Tip: For best results with objects that are to be
brought into Autodesk VIZ, collapse any animation
layers before saving the objects.
Interfa ce
There are two types of dialogs based on whether
youassignaLayercontrollertoapositionorscale
track, or to a rotation track.
List W indow—Displays all Layer controllers for the
selected object, along with their respective weight
value.
Set Active—Determines on which layer your
animation keys are set. The active controller is
marked with an arrow in the list.
Tip: You can also switch between active layers from
the drop-down list on the Animation Layers (page
2–326) toolbar.
