The drop-down options for Start Speed
2.
Select Random Between Two Constants, and set the numbers to
1
and
5.
3.
Check out the results in the Scene view.
4.
Set the Start Speed to
0.5
.
Slowing the Start Speed shortens the plume and makes it denser.
Let's look at the size next. Just as with the Start Lifetime, a bit of variation will improve things.
5.
Click the drop-down arrow at the right of the Start Size, and select Random
Between Two Constants.
6.
Set the values to
0.75
and
1.2
.
Now as the particles reach the top of the plume and pop out of existence, you can see the new
variation in size.
So far, you have seen random values. Let's have a look at the Gradient option for the Start Color.
Most of the settings in the top section affect the particle system as a whole over its lifetime as will
become clear when you specify a color gradient for the Start Color.
7.
In the options for Start Color, select Gradient.
8.
Click on the color bar to open the Gradient Editor (Figure
