Hi Peer, just to make sure I understand, you're talking about setting the .hidden property from inside some of your own script code, not about setting it using the regular MoI UI, right?

Yes.

Yes, that's correct, if it did try to do the same thing it could have some potentially strange effects. Like if you set .hidden = false on a child object, it would probably be weird for hidden = false to be set on parent groups which would cause objects in other sibling sub trees of the group to get hidden.

You'll probably need to do the showing first. If the object you want to have shown is inside of a group then set hidden = false on the top level group:

obj.hidden = false;
var toplevel = obj.getTopLevelParent();
if ( toplevel.isGroup )
   toplevel.hidden = false;

Do that on all objects you want shown.

Then set .hidden = true on stuff that you want hidden.
