Scatter treats multiple host objects as one with combined surface area (or volume). If you set Scatter to produce 100 instances of a guest object over two host objects, it does not produce 100 for each host. Instead, it produces 100 randomly distributed instances over both host objects' combined surface area (or volume).

This example shows how the Avoid Collisions function works. Higher values result in larger distance between instances.

Camera Clipping

Section
Enable– When enabled, instances are limited to a camera view. The rest are clipped away. This option may improve scene parsing performance and lower memory requirements. It is disabled by default.

Extend View – Specifies an extension to the camera view in all directions. All instances inside the Extend View are not clipped.

Override Clipping - When enabled, the near and far threshold distances from the camera are overridden by the Clipping Near and Clipping Far values.

Clipping Near - Specifies the near threshold distance from the camera, when Override Clipping option is used. The near threshold value determines the minimum distance from the camera, before which instances are clipped.

Clipping Far - Specifies the far threshold distance from the camera, when Override Clipping option is used. The far threshold distance determines the maximum distance away from the camera, after which instances are clipped.

Notes

Fancy Bullets

  • V-Ray 6 provides the option for multiple special objects to be added in combination with a single group/component. This allows for Fur, Scatter, and Displacement special objects to be used simultaneously. Multiple Fur and Scatter assets can be added to a single object.
  • Special objects can be removed from geometry by double-clicking on the group/component, selecting the special object's widget, and then selecting the Erase option from the context menu (right-click to open the context menu).
  • When Mesh Light or Clipper are applied, no other special objects are allowed.
  • The Scatter Density map currently does not support raytraced textures.
  • Curve objects need to be grouped via G shortcut on windows or command + G on macOS to be added as Scatter Area Modifiers.
  • If Scatter is applied to a spline closing a face, its segments (edges of the face) are treated as individual splines.
  • Apply a material with 0 opacity for host objects that you don’t want visible in the rendered image.
  • Scene units in SketchUp are always calculated in inches.
