Velocity over Lifetime module

The Velocity over Lifetime module allows you to control the velocity of particles over their lifetime.

Properties

Property Function
Linear X, Y, Z Linear velocity of particles in the X, Y and Z axes.
Space Specifies whether the Linear X, Y, Z axes refer to local or world space.
Orbital X, Y, Z Orbital velocity of particles around the X, Y and Z axes.
Offset X, Y, Z The position of the center of orbit, for orbiting particles.
Radial Radial velocity of particles away from/towards the center position.
Speed Modifier Applies a multiplier to the speed of particles, along/around their current direction of travel.

Details

To create particles that drift in a particular direction, use the Linear X, Y and Z curves.

To create effects with particles that spin around a center position, use the Orbital velocity values. Additionally, you can propel particles towards or away from a center position using the Radial velocity values. You can define a custom center of rotation for each particle by using the Offset value.

You can also use this module to adjust the speed of the particles in the Particle SystemA component that simulates fluid entities such as liquids, clouds and flames by generating and animating large numbers of small 2D images in the scene. More info

without affecting their direction, by leaving all the above values at zero and only modifying the Speed Modifier value.
