Quote: "Is there a way to have segments appear or disappear as a result of a script? Basically the effect I am trying to achieve is that when a player enters through a specific door, he enters a trigger zone that makes the door disappear so the player cannot go back the way he came. I wouldn't mind rendering the door useless but the game is supposed to be about the mystical and unknown so i want the door to completely vanish"
No, scripts cannot control segments. Scripts only have control on dynamic entities... and post effect shaders... and the global setup file, title page, game won/completed (located in the languagebank\english\gamebank\FOLDER).
If the door (particularly the frame part itself) does not jut out from the wall too much, what you could do is create a wall entity and texture with the same texture the wall uses. Then you make it dynamic and have it spawn with collision on to cover the door. The player can hit a trigger and that trigger would spawn the wall entity to cover the door. however, in order to pull it off so the door cannot be seen, the frame can't stick out to where it would poke through the wall.
There's no problem that can't be solved without applying a little scripting.
