BIP Files
BIP files contain skeletal size and limb rotation
data for bipeds. This is the native character studio
motion file format.

Bipedisa3dsMaxsystemprovidedwiththe
character studio product. It provides the
armature used to pose a character, and facil ities
to animate it using either footsteps or f reeform
animation.
Biped Dynamics
Biped dynamics c alculate a biped’s airborne
trajectory, the bending of its knee or knees on
landing, and the biped p os ition so it maintains
balance when the spine is rotated. When the
position or animation of the biped change,
dynamics cause the biped to adapt.
There are six parameters that affect biped
dynamics. Three are in t he Body section of the Key
Info rollout (page 2–954):
• Balance Factor (page 3–914)
• Dynamics Blend (page 3–932)
• Ballistic Tension (page 3–914)

Biped Playback
Biped Playback on the Biped rollout (page 2–936)
plays the animation for all bipeds in a scene (unless
you use the Display Preferences dialog to exclude
them). This playback mo de usually gives real-time
playback, which you might not get if you use the
3ds Max viewport animation Play button.
In Biped Playback mode, the biped is displayed as
bones only, with no other scene objects visible.
Birth Event
A birth event is a special type of local event (page
3–963) that always comes at the start of a particle
flow (page 3–942), immediately after the global
event (page 3–949).Itsfirstaction (page 3–903)
is a Birth operator (page 2–143) or Birth Script
operator (page 2–145).Thebirtheventcancontain
any number of additional actions, and c an be
succeeded by any number of additional events.
