Original (left) and with VEN selected by the range selectors, Based On set to Character, Shape set to Triangle, and Scale set to 40% (right)
If you have only one selector, Mode specifies the interaction between the selector and the text. With one
Mode
selector, you can use the Subtract mode to invert the selector; other modes do not have an effect on the layer. If you
have multiple selectors, Mode specifies the way each selector combines with the selectors above it, similar to how
multiple masks combine when you apply a mask mode. For example, if your first Range selector includes characters
20-80 and is set to Add mode and your second Range selector includes characters 50-55 and is set to Subtract mode,
the resulting selection includes only characters 20-49 and 56-80, subtracting 50-55 from the range.
Specifies how much you want the range of characters to be affected by animator properties. At 0%, the
Amount
animator properties do not affect the characters. At 50%, half of each property value affects the characters. This
option is useful for animating the result of animator properties over time.
Controls how characters are selected between the Start and End of the range. Each option modifies the
Shape
selection by creating gradual transitions between selected characters using the chosen shape. For example, when
animating the y Position values of text characters using Ramp Down, the characters gradually move at an angle from
bottom left to upper right. You can specify Square, Ramp Up, Ramp Down, Triangle, Round, and Smooth.
Original (left) and after selecting the entire word, setting Based On to Characters, animating the y Position value so that the word is at the
bottom of the frame, and setting Shape to Ramp Down (right)
Determines the amount of time the animation takes to transition from one character to another when
Smoothness
you use the Square shape.
Determines the speed of change as selection values change from fully included (high) to
Ease High and Ease Low
fully excluded (low). For example, when Ease High is 100%, the character changes more gradually (eases into the
change) while it is fully to partially selected. When Ease High is -100%, the character changes quickly while it is fully
to partially selected. When Ease Low is 100%, the character changes more gradually (eases into the change) while it
is partially selected to unselected. When Ease Low is -100%, the character changes quickly while it is partially
selected to unselected.
Randomizes the order in which the property is applied to the characters specified by the Range
Randomize Order
selector. (By contrast, when you use the Wiggly selector, the value of the animator property is randomized.)
Calculates the randomized order of a Range selector when the Randomize Order option is set to On.
Random Seed
When Random Seed is zero, the seed is based on its animator group. If you want to duplicate an animator group and
retain the same randomized order as in the original animator group, set Random Seed to a value other than zero.
