Limit Velocity Over Lifetime Module

This module controls how the speed of particles is reduced over their lifetime.

Properties

Property: Function:
Speed Speed limit (split into separate X, Y and Z components if Separate Axes is enabled).
Space Selects whether the speed limitation refers to local or world space (only when Separate Axes is enabled).
Dampen The fraction by which a particle’s speed will be reduced when it exceeds the speed limit.

Details

This effect is very useful for simulating air resistance that slows the particles, especially when a decreasing curve is used to lower the speed limit over time. For example, an explosion or firework initially bursts at great speed but the particles emitted from it rapidly slow down as they pass through the air.
