A light rig usually contains a large number of lights (often more than 20), and as you might imagine, adjusting each light can take a long time. Fortunately, you don't have to. Instead, you can use the Light Control property editor to adjust the intensity and color of every light in the rig at the same time.
If you just created the rig, the Light Control property editor opened automatically.
Otherwise, click the LightControl node, located under the LightRig null in the explorer, to open the property editor.
Adjust the following lighting parameters, as necessary:
Coarse Intensity controls coarse adjustment of all of the lights' intensity values. Use it to make large-scale adjustments to the intensity.
In most cases, you'll probably want to keep this value as low as possible, since the large number of lights in the rig create very bright overall lighting, even if each light's individual intensity is not particularly high.
Fine Intensity controls fine adjustment of all of the lights' intensity values. Once you have set the overall intensity, use this parameter to make smaller-scale adjustments.
Desaturate removes color from the lights. The higher the value, the less color the lights have.
