Yeah, I'm actually trying to make nearly everything so I don't have to rely on the internet, but it's really hard ^^ I think you should read this ticket. If this is the way we are going to better make it compatible straight away : http://trac.wildfiregames.com/ticket/2986 So if you make the sail a separate object, we could just turn it off on You'd have to make a folded one though. The last point is related to http://trac.wildfiregames.com/ticket/131 and his related ticket is http://trac.wildfiregames.com/ticket/1501 If you need help getting in into the game, with all the files and stuff, just ask me.
