Lights

These commands allow you to use different types of lights in your simulation. [They] can help you [illuminate] dark areas of your simulation [and] contribute to making the VR experience more immersive.

Two light commands change the scene light parameters. Using these [commands] is equivalent to setting the light options in the right menu. The three other light commands are dynamic lights.

Spawn Light

When used, this command [gives] you a choice between three different types of lights to spawn:

Point Light: A sphere diffusing light in every direction around it (like a lightbulb).
Spot Light: A cylinder diffusing light from its base in one direction. [You can change] this direction by moving the spot light using the Grab commands.
Rectangular Light: A rectangle diffusing light from one of its sides in one direction. [You can change] this direction by moving the rectangular light using the Grab commands.

Tips

Use the Flashlight or Headlamp for quick inspection of dark areas without permanently altering the scene lighting.
Spawn Light is ideal for setting up persistent lighting in specific areas of your simulation. Remember that spawned lights remain after you exit the command.
Adjusting Sunlight Intensity and World Light Intensity affects the entire scene and is visible to all collaborators.
