Volume Projected

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:

  1. On the Menu bar, click Create -> Volume -> Projected.

  2. Place the Volume Projected object somewhere in the world.
  3. Specify the Volume Projected object parameters.

Volume Projected Parameters#

Options

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.
FOV

Width of the light beam. It is specified as the angle of the beam cone (in degrees).

  • By the minimum value of 10, the beam is the narrowest.
  • By the maximum value of 90, the beam is the widest.
Step

Distance between neighboring Billboards.

  • The lower the step is, the smoother the beam, since more Billboards are rendered.
  • The higher the step, the more discrete the beam, but the higher the performance is.
Velocity Velocity with which Billboards move to the end of the beam (along the Z axis).
Rotation

Angle of Billboards rotation (in degrees). This angle is set for the Billboard at the end of the beam.

  • If positive, all Billboards rotate clockwise.
  • If negative, all Billboards rotate counterclockwise.
