Realistic Lighting Rig

In Layout, clear the scene and create two null objects at the world origin called "LightRigTarget" and "LightRigParent".

Now load up the "Luxigons.lwo" object you created on the last page, and run the "Convert Luxigons" plugin which can be found in the Layout>>Plug-ins>>Generic Plug-ins menu. In the dialog box that appears, call the new lights "SkyLight".

Delete the first original light (called "Light") and also the Luxigons object (without clearing it's decendents). Also, you must make sure you rename "SkyLight(1)" to "ControlSkyLight", as otherwise, expressions will have difficulty in finding the object after a Load From Scene.

Now comes the fun stuff!

Light array created

Multiple object expression assignment

Open up the Spreadsheet and change the property bank to "Light Properties: Basic". Click on ControlSkyLight's intensity entry and then shift click on SkyLight(15)'s intensity to highlight them all. Now click on the little box with the "E" in it and click "yes" to create intensity envelopes for all the lights. Repeat this process for the color property of the lights.

Still in Spreadsheet click on the name entry for ControlSkyLight, shift click on the name entry for SkyLight(15), and then double click anywhere in the highlighted area. This should select all the lights in the Layout viewport.

Creating light envelopes

Close Spreadsheet and open the Graph Editor with all the lights still selected. Use Selection>>Get Layout Selected at the top of the Graph Editor window. Now from the same menu, select "Filter Curves" and enter:

*.Intensity

This will get rid of all the channels we don't want to see. Use Channels>>Create Favourite Set to save this set as "Rig Intensity". Repeat this process (starting from "Get Layout Selected" from the Selection menu) and create the following sets using these filters:

Channel Set Name        Filter 
    Rig Red           *.Color.R
    Rig Green         *.Color.G
    Rig Blue          *.Color.B

On the next page, we'll add expressions to these channels.
