I am trying to make a world in unreal layer by layer without using world machine. Im having difficulty adding adjacent levels and moving my tiles off the origin point. Every time I try it goes back to the center point in world composition. I have read through the guides on the website but I think Im missing something. I also tried making a new level off the persistent and moving it around but it again it snaps back to the origin point in world composition. Im attempting to make the levels and expand out to create the world. Please help me understand what Im doing wrong.
Thank you this helped a lot
Your welcome, I’m glad I could help. Could you please mark my solution as correct so that others with a simular issue can easily find this answer, thank you 
Are you using imported data or sculpting with the built in tools?
Once you enable world composition it’s very straight forward to add adjacent levels. First make sure Enable World Origin Rebasing is off until you really need it.
Then in the levels panel click the Levels drop down → create new level. It is important to make sure the new level is loaded by right clicking on the level in the levels list and clicking “load Level” and “Make Current”, which will turn it’s name blue. Then create a landscape like usual.
Now to add adjacent levels you need to the open world composition map (a small button at the top of the levels panel), you should be able to click and drag that landscape around and place it where you want. Then right click on the tile and you will see an option to “Add adjacent landscape level”, choose a direction to add it, give it a name, and it will automatically create a new landscape of the right size and snapped to the center your original landscape, just click it and drag it into place. Using the sculpting tools will now seamlessly work between the two. If you had sculpted on the first landscape already, there will be a seam you need to fix, just lightly click on the seam with a sculpting brush to get them to line up.
Quick question , and given its not tons different from original poster I decided to ask here initially anyway:
I have four terrains one which I loaded manually ( don’t like WM), the rest I did used adjacent.
Somehow they got moved to lower right of world comp window ( off center):
, see below
So, as you can see the lower image from screenie shows where the 4 terrains were, ( not centered, terrible), and I tried to move one of them ( top left) to middle left Center of wc window as most prob. do, but it will not Snap , lower right of terrain to intesrsection ( 0) of green and red lines.
As you can there is space between terrain and green and red lines . It won’t snap right.
I have snap icons on and I’m not sure where else to look so it will snap right, any ideas ?
