Module
Description
Velocity over Lifetime module
Can control the velocity over the lifetime of the
particle in each axis.
Limit Velocity over Lifetime module
Velocity limit is another term for dampening or drag.
The Speed limit is the threshold at which the particle
is affected by the amount of dampening.
Force over Lifetime module
Apply forces along any axis using constant values or
curves, or check the Randomize box at the bottom of
the module. Can designate Local or World space.
Color over Lifetime module
Gives a choice of Gradient or Random Between
Two Gradients. Clicking on the field will open up the
Gradient Editor.
Color by Speed module
Displaying color based on speed effectively mimics
Doppler imaging. Set the color gradient with the
Color property, where the min speed represents the
left margin of the color gradient and the max speed
represents the right side of the color gradient, and
the color gradient is mapped to the speed scale
proportionally.
Size over Lifetime module
You have the option of using a curve editor, or
choosing randomization between two constants or
two curves.
Size by Speed module
Same options as Size over Lifetime of using a curve
editor, or choosing randomization between two
constants or two curves.
