Timing group
Controls how keys are generated over time.
Start Time Specifies the first frame to generate keys, which is the first frame
to be considered for the solution. Default=0.
TIP If you set a start time that's later than a keyframe-animated object's last
animation frame, you may get unexpected motion during the interim frames. For
example, if you animate a box's position from frames 0 to 10, and then use the
box in a dynamics simulation that starts at frame 20, the box will move between
frames 10 and 20 because of the Bezier controller's default interpolation. To avoid
this, before solving the simulation, set the last animation keyframe's Out tangent
type to Linear or Step; see
Bezier Controllers on page 3138. Alternatively, set the last
key of the keyframed "input motion" after the start time of the simulation, or set
a start time before the last key.
End Time Specifies the last key considered for the solution. This spinner is
set to the last frame of the active segment on page 7898 when you create a new
