Example Scene

...

In this example, we are using a simple interior scene with several Corona lights. The ceiling lights have been instanced and grouped together in the Corona Lister. To change and affect all the values of instanced lights, simply change the parameter of a single light. The side rectangle lights and floor lamp lights are listed separately in the Corona Lister because they are unique and must be adjusted individually to achieve the desired lighting effect. Also, there are multiple Corona Cameras in the scene which are listed in the Corona Lister. All settings can be quickly changed and managed from here.using the Corona Lister.
