Well, you can't export any trees or rocks from any version of Vue, for one thing, but you CAN export terrains. Vue will "fake" the materials and save them as texture maps and bump maps and allow you to export them along with the terrain object in several image file formats. Lightwave uses Targa, right? Vue can do that, but again, that's all Vue will export , is the terrains. E-on also makes a plugin for Lightwave, called Ozone, which allows for the creation of Vue atmospheres within the Lightwave program itself.
