Fade
Function
This function multiplies the RGBA channels. It differs from Brightness
in that Fade effects the Alpha channel as well. If you want individual
channel control, use Mult.
A neat trick is to fade to 0. This will effectively deactivate all nodes above the Fade node.
Note you don't have to worry about premultiplication with the Fade node, as it treats the RGBA channels evenly.
