Modulate by Volume

This compound modifies particle or object parameter values using the volume of an object and a profile curve.

Plug its Value (scalar) output into any compound's port that accepts scalar data, such as the Speed, Mass, and Size ports on the Emit compound.

If you use this compound with the Emit compound, you need to plug another instance of its Value output into a Set Data compound for the type of data you're modifying (such as Set Particle Size if you're modifying the Size parameter). Then plug this Set Data compound into a port on the ICETree node so that the data is evaluated at every frame instead of just once at emission.

For more information, see Modifying Particle Values by Null or Volume [ICE Particle Simulations].

Tasks: Particles/Modifiers,Deformation/Modifiers

Output Ports: Value

Geometry	The object whose volume you want to use to modulate the particle's or object's values. This must be an object with geometry. Plug the object's Value output into this port.
Falloff Profile	This graph determines the shape of how the particle or object values are modified when they are within the volume. The graph represents the Multiplier value (Y axis of the graph) over the Falloff Distance (X axis of the graph).
Falloff Distance	The distance in Softimage units over which the particle or object values are modified.
Multiplier	Multiplies the current value of the parameter you're modifying.
