Pattern Input Number Integer (Available when ‘Pattern’ is set to ‘Pattern Input’)Selects the index of the input pattern which should be scattered.

Pattern Input Distribution Integer (Available when ‘Pattern’ is set to ‘Pattern Input’)The method used to select which of the input patterns should be scattered on a given spline:
- Random: a pattern is randomly selected;
- Along Spline: The pattern index increases gradually along the spline;
- Pattern Index: Loops over the index of input patterns along each spline;
- Spline Index: Loops over the index of input patterns from one spline to the next in the list of input splines.

Distribution Jittering Float (Available when ‘Pattern Input Distribution’ is set to ‘Along Spline’)Randomly increases or decreases the selected index of patterns on the spline.

First Pattern Input Index Integer (Available when ‘Override First Pattern’ is set to ‘True’)The index of the pattern that should be placed at the start of each spline.

Override Last Pattern BooleanManually select the index of the pattern that should be placed at the end of each spline.

Last Pattern Input Index Integer (Available when ‘Override Last Pattern’ is set to ‘True’)The index of the pattern that should be placed at the end of each spline.

Duplicates

Distribution Mode IntegerThe method used to place the duplicate patterns:
- Linear: duplicates are evenly spaced along the spline’s normal from the pattern’s original location;
- Circular: duplicated are arranged along a virtual circle centered on the spline at the pattern’s original location.

Duplicates Amount IntegerThe number of duplicated patterns.

Offset Float2 (Available when ‘Distribution Mode’ is set to ‘Linear’)Applies an offset to the duplicates’ positions along the spline’s tangent (parallel) and normal (perpendicular).
Duplicates on opposite sides of the spline are moved in opposite directions.

Offset Center Float2 (Available when ‘Distribution Mode’ is set to ‘Linear’)Applies an offset to the duplicates along the spline on X (parallel) and Y (perpendicular).

Offset Distance Float (Available when ‘Distribution Mode’ is set to ‘Circular’)The radius of the virtual circle along which duplicates are distributed.

Rotation FloatRotates the virtual circle along which duplicates are distributed.

Offset Start/End Attenuation Float2Factors in the distance from the midpoint of the spline to its Start and End, when applying offsets to duplicates.
This means offsets are decreased for duplicates closer to a spline’s extremities.

Offset Attenuation by Thickness FloatFactors in the spline’s thickness when applying offsets to duplicates.
This means offsets are decreased for duplicates on a portion of a spline with a lower thickness.

Size

Size Mode IntegerThe method of setting the size of the scattered patterns:
- Normal: Size is controlled uniformly using a global ‘Scale’ parameter;
- Use Thickness from Spline: Size is driven by the spline’s thickness.

Thickness Affects Integer (Available when ‘Size Mode’ is set to ‘Use Thickness from Spline’)Specifies which axis of a pattern’s scale should be driven by the spline’s thickness:

• X & Y: Thickness is multiplied against the size in both the X and Y axes;
  - X: Thickness is multiplied against the size on the X axis only;
• Y: Thickness is multiplied against the size on the Y axis only.
  When not multiplied, the pattern’s original scale is the full span of the image.
  This means in the ‘X’ mode, the size in the Y axis is the full span of the image and needs to be tweaked using the Size parameter. The same applied for size in the X axis when using the ‘Y’ mode.

Size Float2The original size of patterns in X and Y before other adjustments are made by other parameters.

Size Random Float2Applies a random multiplier up to the specified value for reducing the size of the patterns in X and Y.

Thickness Scale Float (Available when ‘Size Mode’ is set to ‘Use Thickness from Spline’)An additional multiplier for the scale of the patterns when driven by the spline’s thickness.

Scale Float (Available when ‘Size Mode’ is set to ‘Normal’)A global control for the size of all patterns, where 1 is the full span of the image.
Scaling is applied relatively to a pattern’s pivot. The pivot position can be offset using the ‘Shape Pivot’ parameter.

Scale Random FloatApplies a random multiplier up to the specified value for decreasing the size of the patterns.

Scale Map Input Multiplier FloatControls the intensity of the Scale Map input. This map acts as a multiplier for the current size of the patterns.
The effect of this map is combined with the other parameters in the ‘Size’ group.

Scale Input Sampling Mode Texture SpaceThe method of mapping the values in the Scale Map to the splines:
- Texture space: The values are applied to the splines where they would be if placed in a texture using the texture’s UV coordinates. This effectively applies the value to the splines ‘in place’;
- Horizontal along spline: The values are applied to the encoded splines’ coordinates directly (see Spline Coords input), where each row is applied to a different spline from top to bottom;
- Hor. along spline (rand. offset X): The values are applied to the encoded splines’ coordinates directly (see Spline Coords input), with a random horizontal offset in the Scale map for each spline (I.e., each row in Spline Coords);
- Hor. along spline (rand. offset Y): The values are applied to the encoded splines’ coordinates directly (see Spline Coords input), with a random vertical offset in the Scale map for each spline (I.e., each row in Spline Coords).

Start/End Attenuation Float2Factors in the distance from the midpoint of the spline to its Start and End when scaling the patterns.
This means size is decreased for patterns closer to a spline’s extremities.
