This is something that a lot of people will like:
BETTER EDITOR (editor,not Devkit) (i am back i was in an beach)
and BETTER IN GAME EDITOR (the editor you open with shift+ f6)
Flip The buildings: plz nelson add this, i needed it soo much. i need it in 3.0 or 4.0
new objetcs to make houses (walls, walls with windows, doorframes, roof,etc) but not like the pine,birch,maple,brick and metal buildables, some like concrete,modern floors, glass roofs,etc
option to make the objects from map editor more larger from down. because sometimes i want to put houses at the top of a liberator (idk why) but i cant because if i pu them you can see some hidden parts and they look bad.
also, an npc maker and special objects maker (books,notes, water tanks, fuel tanks,etc)
i know a guy already maked an topic with npc makers, but i want to add that in this topic because is an good idea.
The problem with having sections of buildings in the editor would be that the maps would be filled with lots of little objects, with lots of little polygons, rather than several large objects, with as few polygons as necessary.
