I know this doesn't look like a Flags Enumeration/bitmask right now, but I assure you it is. This is the possible states that a Presentation Node can be in, and it is almost certain that its potential states will increase in the future. So don't treat it like a straight up enumeration.
Type: int32
Valid Enum Values
  • None: 0
  • Invisible: 1
    If this is set, the game recommends that you not show this node. But you know your life, do what you've got to do.
  • Obscured: 2
    Turns out Presentation Nodes can also be obscured. If they are, this is set.
