Light Mixer Editor

The light mixer editor is a convenient window to allow you to edit multiple lights in the same interface.

Opening Light Mixer

You can open the light mixer editor from the scene properties and clicking on the Open Light Mixer Editor

Or, you can open it from the Object Context Menu.

To create a group, click the + button on the right. A default name will be given to the group.

Once you've created your group, you can add lights from the scene using the drop-down list, or do a search using the funnel icon.

Once you've added the lights to a group, you should see something like this.

As you can see, the UI presents some of the more common parameters that you would edit on a light. From left to right:

The "-" button allows you to remove the selected light from the selected group
The name of the light that you added
Temp: this allows you to switch over specifying a color temperature for your light.
Intensity: the intensity of the light
Exposure: the exposure of the light
The light bulb icon allows you to solo the selected light. If you solo a light, all other lights in the scene will be off
The eyeball icon allows you to mute a light, meaning that the light will be turned off in the scene.
