Hi Martin, Often times you can use either a nodemask or Switch node to do the same thing. I look at nodemasks as an encoding of a node state that is more than just on or off. For example, a nodemask can have one bit indicate it is a shadow caster and another bit for shadow receiver. When a nodemask can have a state other than on/off and you want to turn nodes on/off, it's often cleaner to use a Switch node than to keep track of Node and nodemask pairs.
