Once a Scatter is associated with its host, you can control the scale and rotation range of the scattered objects.

Scale – Specifies a scale range for the scattered objects.

Rotation – Specifies a rotation range for the scattered objects.

Scale Multiplier – Specifies a uniform scale multiplier for the scattered objects. This value is combined with the random scaling, so that once you have a suitable Scale range, it allows for scaling up and down the whole composition of scattered objects.
