env_dynlight

Dynamic light source with adjustable light beam angle. It can work both as a spot light, and as an omnidirectional light. It also allows you to project textures/videos onto the level geometry, which can be used, for example, to implement a projector at a location with a cinema.

Properties​

  • Name - Light source targetname
  • Parent - Targetname of object which light source will be attached to
  • Light Color - Light color (in format R G B)
  • Light Distance - Light attenuation radius (in units)
  • Brightness - Light brightness
  • Cutoff Angle - Light beam angle (in degrees)
  • Texture - Path to texture (for projecting)
  • Media file - Path to video file (for projecting)

Spawnflags​

  • Start Off - Light source appears initially turned off
  • Disable Shadows - Disables shadow mapping for light source
  • Disable Bump - Disables normal-mapping for light source
Tip

To make the light source omnidirectional, you need to set the value to 0 for the Cutoff Angle parameter

Warning

To avoid shadow artifacts, it is advisable not to set a value higher than 180 degrees for the Cutoff Angle parameter
