Exclude Orbx Landclass/Mesh

Hi guys, after making an already existing island, I made the stupid mistake of editing the mesh with Orbx LC/mesh enabled. I would like to share this pack with others who don't use Orbx
I spent countless hours editing the mesh but by the looks of it, I will have to re-edit after I disable. If that is the case, my question is, how does one go about excluding the Orbx mesh that's injected into P3D via Orbx Vector?

Hope that makes sense. Thanks in advance!
