I cant find the answer to this I want my world to seam endless how do I not see the end of map maybe a endless ocean or must I just add huge mountain range
There are many ways to hide the end of the map:

It depends on your kind of map which one you should use 
Hello, I have a similar question. Can I put a big trigger box/transparent box to reduce the playable zone inside a landscape?
Thanks!
Pls, open a new thread when you have specific questions
It depends on what you want to do with the trigger box -> there are collision volumes that you can place so that the player cant walk to certain areas of your map
