[Amnesiaplayer]

i know that.... but if i go it's going to one VIEW so i can't see the back , the back i can only see if i turn the whole map... but no one understands e is there i video where someone makes a BIG map... but i still cannot tell.. how did they Made so big maps! like DnAlange did (streets) or orginal amnesia the place where you need to go to the cellar,laboratory... that big maps....i even't can't reach there.. What i do.. if i zoom out... nothing happens it's too big... i hope later there will be a tutorial how to build BIG worlds like the other makers did....
