Save Cars and there states on maps

Hi,
I know this question has been asked very often now but I cant find a usefull tutorial.

I would like to save a map and the objects like cars and Props on it so I dont have to place them every time when I load the map again.

If there is a video available I would like to see it or a step by step written tutorial would be nice too.

I know there is something in the world editor where I have to enable "canSafe" to safe the car on a map but its not there anymore when I load the map again after saving it.

Thanks in advance!

 

No, Not that I know of.

 

place the cars where you want, open the f11 editor and save the map
then the cars will spawn in those places next time

 

Well yeah, thats what I have done but it doesnt work...
