U can download a demo version of 3d exploration from the home website. Lightwave files are compatible with vue 4, the only hitch is that it can't read LW 6/6.5/7 files. I hope this helps. aside from that, you could try the link above. Its a converter's paradise for different formats...but I am not sure if it will have the conversion u are seeking.
