Some HUDs contain controls for eects. For example, the 2D Particle Emitter HUD contains
a single control that provides a visual way to manipulate three particle system parameters:
Emission Range, Emission Angle, and Speed. These unique controls allow you to set multiple
parameters simultaneously and in an intuitive way.
When multiple eects are applied to an object, you can cycle through the eects’ HUDs. A small
downward-facing arrow next to the HUD name indicates that additional eects are applied to
the selected object.
The arrow indicates
multiple control sets
for the selected object.
Note: It is easier to enter a specic value for a slider parameter in the Inspector.
