Hello,
I am enjoying iClone 8. The manual was helpful, but there are some features I have not located documentation on.
I created a project in iClone 8, and created a sphere (which is labeled Ball in the Scene Collection. 
I deleted the default project lights and loaded Aqua from Templates>Atmosphere. (See attached image.)
Looking at the Scene tab Collection, I notice several LightSets. Each LightSet has a child light attached to it. 
There are two spheres situated in the center of the lighting setup. Each sphere has another sphere inside.
One external sphere is attached to LightSet 3. However, the smaller sphere inside is attached to LightSet 2.
I am not certain what the external or internal spheres are for, or how they relate to the actual lights.
Is there any documentation for LightSets?
Thanks,



Nathan
