Rig Lighting

Last Update 2 years ago

Light objects in your scene can illuminate certain targeted areas.

Using the Create Menu you can add in multiple types of lights with different physical properties.

Some light types include real-world riggings, such as box and spotlight stands, and others can just be placed anywhere in 3D space.

All lights have the following properties:

Volumetric VFX	This allows you to turn on or off the simulated volumetric light effect. Depending on the look of your scene, this may or may not be desired.
GI/Indirect Mode (Pro Only)	This allows you to change the indirect light/global illumination mode. See below for more info.
Light Intensity (Lumens)	This allows you to set the intensity/brightness of the light in Lumens. This value is highly approximated and is not a 1:1 recreation of light intensity.
Spot Angle	This allows you to change the angle of the spotlight. This only applies to spotlights.
Temperature Preset	This allows you to set the temperature of the light to a preset based on real-world bulb types.
Temperature	If the above option is set to "Custom", then it can be set manually. This value is in Kelvin and ranges from 1000k (red) to 10,000k (blue);
Light Rotation	If a Box Light or Spot Light with Stand is being used, this allows you to change the rotation of the light source relative to it's physical stand.

Indirect / Global Illumination

This is only available for Pro Users.

Each light that can be added to your scene has a GI/Indirect mode dropdown that allows you to change the GI effect.

The three options are:

None	Plain and simple, this turns off all indirect/GI simulation and only uses the light's direct influence.
Multiplied GI	This simulates indirect light by multiplying the light's intensity around the source. The results of this effect will vary depending on light placement and what other objects are influenced by the light. In unideal situations, this mode can result in a haze around the light source.
RayTraced GI	A Raytraced version of Indirect/GI Lighting. See the article on Ray Tracing linked below.

See the examples below for the difference in modes.
