Count – Defines an exact number of instances to scatter - either overall, or per area in the case of scattering defined by density (Per Square option). The number is always limited by the Instance Count Limit option. See the Count example below for more information.

Per Square – When enabled, the number of instances to scatter is defined by density (Count per square having the given edge length). The number of instances is always limited by the Instance Count Limit option. See the Per Square example below for more information. 

Square Size – The specified value is the edge length of a square defining an area for computing the scatter density. The length is measured in world units.

Density Texture 1 – Allows a black-and-white texture map to be assigned. The map determines how the instances are scattered on the surface. User attributes can also be assigned to determine the scattering.

Using a Density texture generates a brand new instance distribution. The total number of instances (approximate to the Count value) is preserved and distributed on all surfaces that correspond to map values above 0 (parts of the map not being purely black). Instances are more likely to be generated in areas with higher Density Texture values than darker ones.

Pattern – Determines a pattern for the scattering. See the Pattern example below for more information.

Grid – Rectangular grid.
Running Grid – Rectangular grid with every other row offset by half of the grid spacing.
Hexagonal Grid – Arranges instances into hexagons.

Lock V – When enabled, the values of the V coordinate for Spacing, Jitter and Offset are locked to the U coordinate's values. See the Offset examples below for more information.

Spacing – Scales the pattern in UV space. When Spacing is set to 1, the pattern occupies the whole space. When Spacing is set to 0.5, the pattern is repeated twice. See the Spacing example below for more information.

Jitter – Determines what percentage of the instances are randomly placed. When Jitter is set to 0, all instances are placed according to the UVW mapping. When Jitter is set to 1, all instances are randomly placed. See the Jitter example below for more information.

Offset – Offsets the pattern by the given value. Keep in mind that 0 and 1 Offset gives the same result, as 1 moves the pattern by one whole repetition. See the Offset examples below for more information.
