Speed animation changes the speed of a particle after emission.
You can configure Acceleration/Deceleration from the Speed item on the particle set panel. You can cause particles to speed up or slow down.
Multiplies particle speeds by a specified value every frame.
Use the following parameters to configure Acceleration/Deceleration.
Parameters | Description |
---|---|
Ratio | Specifies the value by which particle speeds are multiplied every frame. Practical values range from 0.9 to 1.1, but you can also use values beyond this range. |
The figure below shows how the speed of a moving particle changes as the Ratio is applied.
You can configure Gravity from the Speed item on the particle set panel. You can cause a particle to move in the specified direction with inertia in a realistic manner.
Multiplies the direction by a specified value every frame to change the particle's direction.
Use the following parameters to configure Gravity.
Parameters | Description |
---|---|
Direction: | Specifies the direction in which the particle moves in terms of X, Y, and Z values. Valid values range between -1 and 1. |
Speed | Specifies the value to add every frame to the particle's speed. |
The figure below shows how the speed of a moving particle changes when Gravity is configured.
You can set randomness (speed) for animations using the Speed item on the Particle Set panel. You can make each particle gradually speed up.
Adds a random value to the particle's speed.
Use the following parameters to configure randomness (velocity).
Parameters | Description |
---|---|
Strength | Specifies the value added to the particle's speed. |
Frame Interval | Specifies the interval for adding values to the particle's speed, as a number of frames. |
(Parent Particle Speed + Child Particle Speed) × Random Number
