12.10 The Time Offset Modifier
With the Keyframe Group contracted to 20 Frames and all Keyframes selected in Object Mode go
to the Properties Editor, Modifier Properties Tab. Click Add Modifier and in the Deform Category
select Time Offset (Figure 12.23).
Figure 12.23
In the Time Offset Modifier panel (Figure 12.24) check
(tick) Custom Range and click on the little triangle to
expand the Custom Range panel. Checking Custom
Range activates the properties.
Leave Start at 1 (Frame 1) but change End to 20
(Keyframes at Frame 1 to 20).
Play the Animation to see your Character continually
walk. The Timeline Cursor travels to Frame 250 then
repeats but the Character walks all the way.
Figure 12.24
The Character is only a rough sketch, therefore, at this
point you may want to refine the Strokes in each Pose by
using the Tools available in Edit Mode or Sculpt Mode.
Alternatively you can draw over the sketches.
Remember: The Character is marking time in the same
position in the Scene. If you want to Animate to walk
across the Scene you would create Poses in Edit Mode
and position the Strokes at intervals in the Scene.
Positioning in Edit Mode creates Keyframes in the
Timeline. You may select and duplicate the Keyframes to
have the Character traverse the Scene.

12.11 Animating the Scene Background
By having the Character marking time as the Animation plays you can create the illusion that the
Character walks in the Scene by animating a Background to traverse the Scene opposite to the
Walk Cycle.
Figure 12.25 shows a simple Background depicting a ground plane and a tree with all Stroke on
the Layer named Grass in the Outliner Editor. Having all the Strokes on the single Layer
simplifies the demonstration.
The Character is left in situ as a reference for positioning the background in the Scene.
