The maximum age of a particle in seconds.

This attribute is automatically set by some of the Emitters compounds.

This attribute must be set to use compounds that set values based on age percentage, such as Modulate Value by Age Percentage.

Particles are not deleted automatically when they reach AgeLimit. There must be nodes in a tree to specifically delete the particles, such as Delete Particle at Age Limit. Or you can use the Kill Particles compound which deletes particles upon reaching their age limit.

You can quickly get and set the AgeLimit attribute using the Get Particle Age Limit and Set Particle Age Limit compounds.

You can also use the Get Particle Age Percentage compound that uses both the Age and AgeLimit attributes with a Divide by Scalar node to get a percentage value.
