The Volume Projected object is used to create light beams from directional light sources, such as car headlights, searchlights or beacon light. It can also be animated to simulate a flow of particles that moves from the light source or even swirls. Only a volume proj material can be assigned to it.
Volume Projected is rendered as a simple particle system. It is a number of Billboards, where each following Billboard is bigger than the previous one.

Creating a Volume Projected Object#
To create a Volume Projected object, perform the following steps:
On the Menu bar, click Create -> Volume -> Projected.
- Place the Volume Projected object somewhere in the world.
- Specify the Volume Projected object parameters.
Volume Projected Parameters#
In the Volume Projected section (Parameters window -> Node tab), you can adjust the following parameters of the Volume Projected object:
|Size||Size of the smallest Billboard in units. By the minimum value of 0, Volume Projected is not rendered at all.|
|Radius||Length of the light beam along the Z axis, in units.|
Width of the light beam. It is specified as the angle of the beam cone (in degrees).
Distance between neighboring Billboards.
|Velocity||Velocity with which Billboards move to the end of the beam (along the Z axis).|
Angle of Billboards rotation (in degrees). This angle is set for the Billboard at the end of the beam.
Positive rotation angle
