•
Controls the ends of scribble lines. Use Round for stroked lines with semicircular ends; use Butt for
End Cap
stroked lines with squared ends; and use Projecting for stroked lines with squared ends that extend half the line width
beyond the end of the line, making the weight of the line extend equally in all directions around the line. This option
is enabled only if Fill Type is set to Centered Edge.
•
Specifies how the corners of a scribble line appear. Use Round for stroked lines with rounded corners; use
Join
Bevel for stroked lines with squared corners; and use Miter for stroked lines with pointed corners.
•
Controls when the effect switches from a miter (pointed) join to a bevel (squared-off) join. Specify a
Miter Limit
value between 1 and 500. For example, if the value is set to the default value of 4, the effect switches from a miter to
a bevel join when the length of the point reaches four times the stroke weight. A miter value of 1 results in a bevel
join. It is enabled if Join is set to the Miter option.
•
Specifies how changes to the effect's Start and End options in the Timeline panel are applied;
Start/End Apply To
Scribble Result affects the scribble in the order in which it is drawn, and Mask Path follows the path of the mask to
create more continuous drawing in or out of the scribble.
Specifies Scribble color.
Color
Specifies the opacity of the lines in the scribble.
Opacity
Specifies the angle of the scribbled stroke.
Angle
Specifies the width of the stroke. Specify a value from 0.1 to 50.
Stroke Width
Specify the curviness, spacing, and overlap of the scribbled line.
Stroke Options
•
Controls the amount of curve at the end of each scribbled stroke. Specify a value between 0 and 100
Curviness
degrees.
•
Determines the amount of variance the curviness values can have at each end point. Specify
Curviness Variation
a value between 0 and 100 percent. A value of 0 gives the scribble sharp corners, while a value of 100 makes the
scribble loopy.
•
Spacing and Spacing Variation
Specify a value between 0 and 50 percent. Setting a value equal to the stroke width value makes the lines fall next to
each other.
•
Determines whether the scribble ends at the path, inside the path, or outside the path. Specify 0 to
Path Overlap
make it end at the path, negative values to make it end inside, and positive values to make it end outside. Path Overlap
Variation determines how much each stroke can vary from the value specified for Path Overlap.
Control the point along the stroke where the stroke starts and ends.
Start, End
Enabled when Scribble is set to All Masks. When this control is selected, the start and end
Fill Paths Sequentially
values apply to the combined length of the scribbles for all masks. When it is not selected, the start and end values
apply independently to the scribble for each mask.
Specifies an animation style: Static keeps the scribble constant over time; Jumpy changes from one
Wiggle Type
scribble to the next abruptly; and Smooth changes from one scribble to the next smoothly.
Controls how frequently a new scribble is generated when the Wiggle Type control is set to Smooth
Wiggles/Second
or Jumpy.
Generates random scribbles. This control is most useful when the Wiggle Type control is set to Static.
Random Seed
Controls the composition of the effect on the original layer.
Composite
(specified in pixels) Control the amount of space between lines and zigzags.
