When I add water, I encounter only one source of difficulty: adding it results in all objects, regions, ect. including the water itself, get moved sideways a certain amount. Their height stays the same, but their horizonal position is altered. Only the terrain itself dosn't get moved.

To add water, I add a world FX file and make an addition to the world's REQ file. How could this problem be caused, and how to I fix it?

Since I don't see how the REQ file modifications could have caused this problem, here is my FX file. It's an almost exact copy of the Kashyyk one (I only removed the FogCloud effect), since I am using Kashyyk water. (Note, my map may have a different terrain size than Kashyyk)

no it seems you have made a new terrain......with not 128x128 or 256x256 1024x1024 as size! make a new one and choose one of those sizes otherwise terrain will move away........
