I had downloadet the demo "normal jumps" neuville29 to get out of the map of neuville. But if i look the demo, theres a nade jump to get on the roof. And i want to know how to get out of the map

ANd on Carentan (dont know number):
Its a jump from a window to an other windows and from the window on the roof.
Under the demo you write that its a hard jump and you will find help in the forum (but didnt find).
Can you maybe give me some tips to get these jump?
thx and mfg
