I get weird results bringing my fbx files into UE4 when they have a voronoi node in them in Houdini. I watched a lot of tutorials on this and no one seems to be having this problem. Other people's meshes are seamless and mine aren't put together properly… You can see the different voronoi cells and that's not supposed to happen. I have no idea what's going wrong here and any ideas would be very welcome! Thank you!

I added pictures of the problem and what the mesh is supposed to look like.
