Light Rig
 

I just learned how to make a Light Rig or Soft Spot Rig. I was wondering what controls to add to the Extra Attributes. I was thinking I might need:
Color
Intensity
Penumbra Angle
Dropoff
Use Depth Map Shadows
Dmap Resolution
Dmap Filter Size

I also was wondering how many lights to have in the rig? And what pattern to use? Should I over lap them or just let them touch at the rim?

How do you have your Light Rid set up?
