if I understand this stuff correctly... (lol):
Object.transparent = true
(
http://quest5.net/wiki/Transparent ) you can 'see' the "child" Objects (the "sub" objects held by~within the Object containing them that you're looking at), but you can't interact with those "child" Objects until you open up the container Object that they're within.
Object.scenery = true
(
http://quest5.net/wiki/Scenery and
http://quest5.net/wiki/Interacting_with_objects ) you can't 'see' the "child" objects (of the Room Object that 'contains' them), but you can interact with them still...
Object.visible = false
(
http://quest5.net/wiki/Visible ) makes the object hidden to the person playing the game, a somewhat similar conceptual effect as the "scenery=true"
