Volume Projected

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.

Projected volume is rendered as a simple particle system. It is a number of billboards, where each following billboard is bigger than the previous one.

On the Volume Projected tab of the Parameters window, 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, the 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 most narrow.
  • By the maximum value of 90, the beam is most wide.
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.
