Animating scene objects
Cel animation properties
A cel animation is a sequence of images shown in rapid succession to form an animation.
Each image in the cel animation is a known as a frame, and each has a frame number
indicating its position in the sequence, starting with frame 1.
A cel animation starts playing when its V ISIBLE property is selected in the Keyframe Editor.
Note however, that the cel animation also has a V ISIBLE property in the scene that is
accessible from the Property Browser. Be sure to set the V ISIBLE property in the Property
Browser to F ALSE , otherwise it will start playing immediately upon entering Production mode.
The following table identifies the additional properties that determine how the cel animation
will play. However, these properties need to be set before playing the cel animation. Once
the cel animation is playing, changing these properties will have unpredictable effects.
(Generally, these properties are set up in the frame preceding the frame on which the cel
animation's Visible property is switched on.)
Property What it does and how to make it animate
CelName The cel animation to be displayed. Specify the cel animation to display at the
selected keyframe by dragging it from the Asset Browser and then dropping it into
the C
EL N AME field in the Keyframe Editor or the desired frame on the timeline.
EndFrame Specifies the cel frame at which the cel animation ends.
Manually enter the frame number in the E ND F RAME field in the Keyframe Editor.
Entering 1 means that the animation should run to the end.
EndLoop The cel frame at which the cel animation finishes or stops looping.
Manually enter the frame number in the E ND L OOP field in the Keyframe Editor.
For this property to work, the L OOP property must also be activated in the animation.
Loop When selected, indicates that the cel animation will restart from the frame indicated
by the S
TART L OOP property.
Rate The duration of a cel animation is determined by the number of frames in the cel
animation and the rate at which it is played. By default, the rate is the number of
frames per second supported by the target output format.
Manually enter the number of frames per second to be used at the selected
keyframe in the Rate field in the Keyframe Editor.
StartFrame Specifies the cel frame at which the cel animation starts playing. Manually enter the
frame number in the StartFrame field in the Keyframe Editor.
StartLoop The cel frame at which the cel animation starts when looping.
Manually enter the frame number in the S TART L OOP field in the Keyframe Editor.
For this property to work, the L OOP property must also be activated in the animation.
