so I got an email from a helloluxx user, who wanted me to explain, how to affect only some geometry connected to a scene, by the lights connected as well. The material in the video is all provided by Anderson Moreira, who wrote to me.
Be sure to check out his vimeo channel: Andersons Vimeo channel
and in case you are having trouble with anything yourself or have anything you want me to take a look at, etc.
You can email me here: Mail me!
