### 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.

### What Type of Bug are you experiencing?

World Building

### Steps to Reproduce

1. Create a level
2. Add a landscape + deform it with sculpt mode in the landscape edit layer “Layer”
3. Create a new landscape edit layer
4. Go back to selection mode
5. Create a spline blueprint so the landscape can deform to the splines placement (example nodes attached)
6. Add the spline to the level and add some points + move it up.
7. Position the spline over a deformation made from sculpt mode.
8. Set the LandscapeEditLayerName to the new edit layer you created (not the same as the sculpted layer)
9. Set the boolean condition to true and watch the landscape deform.

### Expected Result

I expected the landscape to deform to the same height as the spline, not to create an offset that’s dependent on the deformation on other layers. It should preform as it does when the deformations are in the same edit layer.

### Observed Result

These steps will make the landscape deform with an offset to the spline that’s the same height as the deformation made in another landscape edit layer. Having multiple splines in different edit layers will also produce this. This is the same for both Landscape Splines and Blueprint splines when placed in different edit layers.  
This does however not happen if the spline is in the same landscape edit layer as the premade deformation.

### Platform(s)
