Velocity Over Lifetime module
The Velocity Over Lifetime module allows you to control the velocity of particles over their lifetime.
Properties
| Property | Function |
|---|---|
| X, Y, Z | Velocity in the X, Y and Z axes. |
| Space | Selects whether the X, Y and Z axes refer to local or world space. |
Details
This effect can be used to create an overall drift of particles in a particular direction.
