trimming slab after SEO

[Swimsey]

Im trying to make a surface terrain that i've carved out with SEO. Does anyone know if theres an easy way to trim the nodes down to the "new" surface after SEO? Or do i really have to manually drag the nodes down to wished location?

The blue line is the Meshes reference line. It cannot really be moved and is linked to the Meshes elevation. Every node on your mesh is relative to that blue line. I find that it is generally better to set your Mesh elevation to the lowest point of your terrain, then elevate the rest of your nodes to above that.

Also, is there a reason why your are using a SEO instead of elevating contours? Using a SEO here will severly impact performance... Given the detail of your SEO, are you not able to source the original mesh cooridates in order to use them natively?
