sizeRange

Syntax

member(whichCastmember).modelResource
(whichModelResource).sizeRange.start
modelResourceObjectReference.sizeRange.start
member(whichCastmember).modelResource
(whichModelResource).sizeRange.end
modelResourceObjectReference.sizeRange.end

Description

3D property; when used with a model resource whose type is #particle, this property allows you to get or set the start and end property of the model resource's sizeRange. Particles are measured in world units.

The size of particles in the system is interpolated linearly between sizeRange.start and sizeRange.end over the lifetime of each particle.

This property must be an integer greater than 0, and has a default value of 1.

Example

In this example, mrFount is a model resource of the type #particle. This statement sets the sizeRange properties of mrFount. The first line sets the start value to 4, and the second line sets the end value to 1. The effect of this statement is that the particles of mrFount are size 4 when they first appear, and gradually shrink to a size of 1 during their lifetime.

member("fountain").modelResource("mrFount").sizeRange.start = 4
member("fountain").modelResource("mrFount").sizeRange.end = 1
