Loop This check box is available for scenes and scene animations. It enables
you to control the playback mode. Check this check box to use loop mode.
When the animation reaches the end, it will reset back to the start and run
again.
P.P. This check box is available for scenes and scene animations. It enables
you to control the playback mode. Check this check box to use ping-pong
mode. When the animation reaches the end, it will run backward until it
reaches the start. Unless loop mode is also selected, this will only happen
once.
Infinite This check box is only available for scenes. Check this check box to
make the scene play indefinitely (that is, until Stop
is clicked). If this check
box is unchecked, the scene will play until its end point is reached.
NOTE When a scene is set to Infinite, it can not also loop or ping-pong; so if
you check this check box, the Loop and P.P. check boxes are not available for
your scene.
The Animator Timeline View
The timeline view shows the timelines with keyframes for animation sets,
cameras, and section planes in your scenes.
Use it to visualize and edit the animations.
Timescale Bar
At the top of the timeline view is the timescale bar in seconds. All timelines
start at 0. Right-clicking the timescale bar opens a shortcut menu.
Use the
and icons at the bottom of the Animator tree view to zoom
in and out on the timescale bar.
The default timescale shows around 10 seconds of animation on a standard
screen resolution, zooming in and out has an effect of doubling or halving
the visible area. So, for example, zooming in shows around 5 seconds of
animation, and zooming out shows around 20 seconds.
TIP You can also zoom in and out with mouse wheel while hovering over the
timeline.
Another way of changing the timescale is to use the Zoom box. For example,
type in “1/4”, and press Enter to quarter the visible area. The value you enter
