Creates instances of the input V-Ray Geometry with random transformations, optionally with collision avoidance. The number of scattered instances depends on the density. Density is calculated by the number of instances per square unit. |

This page provides information about the V-Ray Scatter component in Grasshopper.

Seed (Integer) – Controls the random seed of the scatter. Changing this value and refreshing gets you a different random distribution.
Collision Detection (Boolean) – When enabled, bounding boxes of instances that overlap other instance bounding boxes are skipped.
Density (Number) – Determines the approximate count of instances in a square unit. The density value can be used with a texture in place. Black color texture discards all instances in the area. Areas colored with white receive maximum density.
Axis Filter (Integer) – Filters the faces used for instance positioning.
All Faces – The points/instances are generated uniformly on all object faces.
Facing Up – The points/instances are placed only on object faces oriented upwards in the scene. Note that host component transformations are ignored.
Orientation (Integer) – Sets the initial orientation of the instances.
World Up – All instances are positioned upright independent of the base/host surface face normals.
Along Normals – The instances are oriented based on the base surface face normals.
Rotation (Domain) – Sets a range for the minimum and maximum angle for the random instance rotation around its up axis.
Scale (Domain) – Sets a range for the minimum and maximum factors for the random instance scaling.
Guest Origin (Integer) – Determines how objects are positioned relative to the random Scatter points.
Bounding box bottom center – The bounding box bottom center of the object matches the Scatter point.
Bounding box volume center – The bounding box volume center snaps to the Scatter point.
Object origin – The original object origin point snaps to the Scatter point.
Weight (Number) – Determines a list of factors for the relative probability of each guest to appear.
• V Geometry (Generic Data) – Sets a list of V Geo objects to scatter.
Host (Generic Data) – Makes a list of meshable geometric objects to scatter the guests over.
• V Geometry (Generic Data) – Sets a V-Ray Geometry output. Can be connected to the V-Ray Render/Geometry slot.
Distribution (Transform) – Sets a data tree of transformations making the guests distribution over the hosts.
