Modulate Value by Age

 
 
 

This compound modifies particle values over their life span depending on their age.

Plug its Value output into Plug its Execute output into any port that accepts a scalar value, such as the Mass, Size, Speed, or Rate ports of the Emit compound.

For more information, see Modifying Particle Values by their Age or Age Percentage [ICE Particle Simulations].

Tasks: Particles/Modifiers

Output Ports: Value

Profile

This graph determines the particle value change over its lifespan in the simulation.

Tip: If you're modifying the particle Size parameter, make sure that the start value isn't 0 (zero) or else the particles will have no size at emission! Just nudge the value up a bit on the Y axis to make it any value above zero.

Base Value

The parameter's value that is represented as a value of 1 in the graph. For example, if you modify the particle Size parameter and you set this to 5, it gives the particles a radius of 5 units when they have reached a value of 1 on the profile curve graph.
