Hello! First of all, let me say that I've already looked for the answer of my problem in the Internet: the only useful discussion I've read is this (http://www.rpgmakervxace.net/topic/21393-newbie-needs-help-with-mapping/?hl=%2Bthin+%2Bwalls) but I still don't understand how to resolve my problem.
My problem is that I want to make the walls thinner than they look like, I mean the perimeter of the room or of the house. I really don't understand how I can do it! I've tried multiple times to follow the instructions of the discussion above, but I don't resolve anything.
Thank you so much in advance.
