Messed up mesh after using voronoi in Houdini

When I import an fbx model from Houdini that’s been edited with a voronoi node I get weird results in Unreal (23.1). Has anyone encountered this before? I’ve watched a lot of tutorials on this and no one seems to be getting this result… It’s always a seamless model for others but mine doesn’t get put together properly it seems. I’m at a loss for ideas what it could be… Any help would be greatly appreciated!
