I have come to the conclusion that this happens when the spline deformation is set to another _landscape edit layer_ than the deformation already made on the landscape. This problem is for both blueprint splines and landscape splines. Here is a video showcasing it: [https://youtu.be/boFSOrqTgPI](https://youtu.be/boFSOrqTgPI) > [@Unwanted Landscape deformation offset when deforming landscape with splines in different edit layer](https://forums.unrealengine.com/t/unwanted-landscape-deformation-offset-when-deforming-landscape-with-splines-in-different-edit-layer/2505503): > > Summary When deforming the landscape based on a spline (using both blueprint and landscape splines), the landscape should “snap” to the spline. However, if the spline is placed or used in a different landscape edit layer than the initial deformation, the landscape will have an offset equal to the height of the landscape’s deformation before the spline was placed.
