Max limit – Limits the maximum number of scattered instances. Note that there is always another mode-dependent parameter (spacing, density, or count) that determines how many instances to scatter. This parameter is intended as a constant value "safety measure" to prevent crashes/freezes from scattering too many instances, e.g., when setting the density too high.

Random seed – Generates a random value, based on the given number to determines the particular random distribution used. Changing the value makes random permutations of the scattered objects.

Scattering mode – Allows selecting between different scattering modes. See the Scattering mode example for a visual representation.

1D - On splines – Scatters instances along splines. Works with both open and closed splines.
2D - On surfaces – Scatters instances on the surface of the selected objects. Works with closed splines too, treating the spline area as the surface to scatter on.
3D - In bounding box – Scatters instances inside the bounding boxes of the selected objects.

Avoid Collisions – When enabled, the instances which collide with other ones are discarded, resulting in no overlaps between instances. Note that when using this feature, the real number of created instances may be lower than the number specified in the settings.

Spacing – This value is a multiplier for enlarging/shrinking the bounding boxes used to detect and remove collisions of the scattered objects. Use lower values to achieve a higher density of the scattered objects at the cost of some minor collisions. Use higher values to keep scattered objects farther apart from each other.

Enabled – When enabled, scattering is limited only to the camera view, and instances that are not visible are clipped away. It is an optimization - it may improve scene parsing performance and lower memory requirements, however, it can cause missing reflections/shadows. To compensate for this, you can use the Extend View parameter.

Mode – Allows to select between different camera clipping methods.

Render Camera – Clips the instances based on the active camera view used for rendering. The clipping is visible in the viewport only when the clipping parameters are changed or if Interactive Rendering is running. This is because, otherwise, the clipping would be too intrusive during regular scene work.
Selected Camera – Uses a selected camera for the clipping. Тhe clipping is always visible.

Camera – Determines which camera to use, when the clipping mode is set to Selected Camera.

Extend View – Specifies a uniform extension to the camera view in all directions, in centimeters. Adds an extra zone beyond the camera view and behind the camera, where the instances are not clipped. This is useful for ensuring correct shadows or reflections from instances that would otherwise be clipped.

Near/Far clipping – When enabled, allows using the Near and Far Distance parameters to control the camera clipping extension.

Near Distance – Specifies the near threshold distance from the camera, in centimeters. Instances closer than this distance are clipped away.

Far Distance – Specifies the far threshold distance from the camera, in centimeters. Instances farther than this value are clipped away.

Distribution mode – Allows selecting between different distribution modes.

Random – Scatters randomly on all mesh and closed spline distribution objects.
UV – Uses the distribution objects' UVW mapping to scatter the instances in regular patterns.

Count – Defines an exact number of instances to scatter overall. When the Per square option is enabled, scatters instances per area, defined by density. The number is always limited by the Config Max. limit option.

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 Config Max. limit option. The specified value is the edge length of a square, which defines an area for computing the scatter density.

Distribution – Specifies a texture map or shader used for instance distribution. White areas of the texture are treated as maximum density, and black areas are treated as areas with no instances.

Pattern – Allows to select between different distribution patterns.

Grid – Rectangular grid.
RunningGrid – Rectangular grid with every other row offset by half of the grid spacing.
HexagonalGrid – Hexagonal point arrangement.

Use planar mapping – When enabled, simple planar UVW mapping is applied to the distribution object and used instead of its existing UVW channel.

Spacing U – Scales the pattern in the U axis - 100% spacing makes the pattern occupy the whole 0-1 UV space; with 50% spacing, the pattern gets repeated 2 times in U.

Spacing V – Scales the pattern in the V axis - 100% spacing makes the pattern occupy the whole 0-1 UV space; with 50% spacing, the pattern gets repeated 2 times in V.

Jitter U – Randomly jitters each instance in the U axis, with 0% being entirely deterministic placement (no jitter) and 100% being entirely random placement.

Jitter V – Randomly jitters each instance in the V axis, with 0% being entirely deterministic placement (no jitter) and 100% being entirely random placement.

Offset U – Offsets the pattern in the U axis. Each 100% added or subtracted moves the pattern by one entire repetition - which means that, e.g., 0% and 100% offsets yield the same result.

Offset V – Offsets the pattern in the V axis. Each 100% added or subtracted moves the pattern by one entire repetition - which means that, e.g., 0% and 100% offsets yield the same result.

Lock V – Locks the V coordinate for Spacing, Jitter, and Offset to the same value as the U coordinate.

Up Mode – Allows selecting between different modes for the up axis.

Local – The up vector of each individual distribute-on object is used to define the slope limitation.
World – The world Y-axis up vector is used for all distribute-on objects to define the slope limitation.

Slope from/to – These values set the range of angles, measured in degrees, between either the Local or the World up vector and the surface normal. Determines how steep the surface can be, before instances are filtered out. Instances scattered outside of this range are erased.

Display mode – Determines how to display scattered instances in the viewport. Affects viewport performance.

None – Instances are not displayed at all.
Dot – Each instance is displayed as a single dot.
Box – Each instance is displayed as a solid box.
Wire box – Each instance is displayed as a wire box.
Full – Each instance is displayed as the full mesh.

Max instances – Maximum number of scattered instances displayed in the viewport. When this limit gets exceeded, some instances are randomly hidden. If increasing this number would display more instances, the label is colored.

Immediate updates – Forces re-computation of the scattering.
