Sorry, I'm really greeny with this mappers stuff... I'm using "A - Z Beginner Full Guide" with Dark Radiant. But still I can't understood, how to create not only "openable" doors, but doorways. As I understood, I should: 0. Create block brush with "make room"; 1. Create "static" door; 2. Assign for the door classname "atdm:mover_door"; 3. Create 2 more copyes of wall, and curtain them away, making doorway... But after that I get "leaking" error. PS: sorry for my bad english...
