Left Border, Right Border
Dene the frames at which the sequence starts and ends.
Loop Border, Loops, Soft
To repeat the sequence, set Loops to the number of repetitions or set Loop Border to the frame
at which the loops should end (the loops will commence immediately after the sequence). Loop
sequences are shaded a lighter gray than the sequence proper. You cannot add keys to loops.
If you want CINEMA 4D to interpolate softly between the loops, enable Soft. Avoid placing a key
near the end of the original sequence, otherwise CINEMA 4D won’t have enough time to smoothly
interpolate, causing ‘jumps’ between the repetitions.
Time Track
You can assign a Time track to the sequence to control the timing of the sequence using a time curve.
For information on creating time curves, look up ‘Time track’ in the index.
Left Inuence, Right Inuence
A sequence can be as long or as short as you wish. However, what happens during the undened
ranges of the track, where there are no sequences? For example, suppose your animation is 90 frames
long and you’ve created a rotation sequence for a robot’s head that starts at frame 30 and ends at
frame 60. The sequence rotates the head from 0° to 180°. What should happen from frames 0 to 29
and from frames 61 to 90, where there is no rotation sequence?
If Left Inuence is enabled for a sequence, CINEMA 4D internally extends the sequence to the left
to ensure that the track has no empty regions left of the selected sequence(s). So in the case of the
rotating head example, the value of rotation at frame 30, i.e. 0°, will be extended to frame 0. Thus the
robot’s head will start with a rotation of 0°. The head stays at a rotation of 0° until frame 30, then it
starts to rotate and reaches a rotation of 180° by frame 60.
Similarly, if Right Inuence is enabled, sequences are extended to the right. The head would then hold
its rotation value of 180° from frames 60 to 90. You can see these spheres of inuence directly in the
Timeline. They are shown as thin grey lines that extend to the left or right of sequences, as shown in
the illustration below.
