Is there a way to walk around in Landscape mountains after you crash or land the hang glider?
Try clicking on the terrain from the editor and play from here? If that doesn’t work try placing a player start and changing the default gametype?
As far as I know that’s not included in the landscape demo -> you would have to do it by yourself. So just get the crash/landing position and spawn your own character/controller 
That makes sense, I’ll give it a try.
Thanks for your help guys!
