With this iExpression you can distribute 3D layers (or other 3D properties) randomly. You can still move layers away from their random position using their keyframe values or the wiggle parameters.
is the minimum of the possible random values. Note that if you use the wiggle or keyframe offset options, the value could become smaller that this.
is the maximum of the possible random values. Note that if you use the wiggle or keyframe offset options, the value could become larger that this.
Use Keyframe Value as Offset
adds the keyframed value of the property to the random value. This allows you to move the property away from its keyframed value using keyframes.
makes the layer wiggle around its random position with the given frequency. If you don't want it to move at all, set the frequency to 0.
denotes up to how much the layer may move away from its random position when it wiggles.
can be modified to get other random values.
Change Over Time
allows to get a new random value for each frame.
