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 PIC.
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 intersection ( 0) of green and red lines.
As you can see there is space between terrain and green and red lines . It won’t snap right.
I’m not sure where else to look so it will snap right, any ideas ?
