The Transforms rollout is part of the Scatter parameters.


Random Translation

Moves the instances From the given distance To the given distance on the corresponding axis. See the Random Translation Example below.

Step Size – Specifies the random step size.

Random Rotation

Rotates the instances From the given degrees up To the given degrees continuously. The Random Rotation occurs in the specific range. See the Random Rotation example below.

Step Size – Specifies the random step size.

Normal Alignment – When a value, different than 0 is entered, the instances are aligned according to the world up axis. This is useful when the host object is curved and the scattered objects need to remain vertical, not follow the curve of the surface. Positive values mean that the instances are aligned to the +Z axis (vertical up) and negative values mean that the instances are aligned to the -Z axis (vertical down). See the Normal Alignment example below.

Preserve Rotation – Preserves the original rotation of the objects. See the Preserve Rotation example below.


SketchUp2023_VRay6.2.2_Scatter_Parameters_RandomRotation



Example: Random Rotation

This example shows how guest objects are rotated in a specific range.

Example: Normal Alignment 

When a value, different than 0 is entered, the instances are aligned according to the world up axis.

Example: Preserve Rotation 

The Preserve Rotation option determines which way the instances are rotated.

X = 0-0; Y = 0-0; Z = 0-0; Preserve Rotation = Off (Guest not rotated)

X = 0-0; Y = 0-0; Z = 0-0; Preserve Rotation = Off; Guest Rotated  = 90

X = 0-0; Y = 0-0; Z = 0-0; Preserve Rotation = On; Guest Rotated  = 90




Random Scale

Scales the instances From the given value To the given value continuously. The Random Scale occurs in the specific range. When Uniform scale is enabled, the X axis values are applied on the whole Distribute-on target object. See the Random Scale Examples below.

Step Size – Specifies the random step size.

Uniform Scaling – When enabled the X axis values are also used for the Y and Z axes.

Preserve Scaling – Preserves the original scaling of the objects.
