LightsGroups

LightGroups is a concept that allows the user to assign multiple Snappers that has lights into groups, and then control the light parameters, such as brightness, color, and shadows for the entire group, rather than having to select one Snapper at a time and then try to apply roughly the same brightness.

A LightGroups object is stored in Space which contains all the individual LightGroup objects which are created from any Snapper that uses lights. Only Snappers have the inbuilt ability to do so with Space.

LightGroup

A single LightGroup object mainly consists of a key that is used to uniquely identify lights that are intended to have the same properties. Each property within a LightGroup is defined in the props collection:

    /**
     * Properties.
     */
    public GProp[] props;

which contains again a key to identify the type of property.

If two different LightGroups were selected, only the main Snapper within the Selection will populate the Light Settings dialog:

But if different LightGroups are grouped together, all of the properties from the different LightGroups will populate the Light Settings dialog. When a user changes a GProp, only LightGroups that share that GProp key will change along:
