Fade nodes on layer

[JoelRose]

In HLS we called it a master lighting channel.

I have separate effects on nodes that that I would like to fade up at the model or whole house level
From seconds 1 to 5 there are supposed to be alternating on, offs ramping up in intensity.

Asking the same question a different way. 
How do you decrease the intensity of a P10 panel after you have created all the effects.
Or how would you fade out l channels at the end of a song.

Started converting about a week ago but liking what I am seeing so far.

At the end of the sequence, add a fade up or ramp up of black to your model group that has all your models (causes everything else to dim).
