Poser only imports lw 5.x versions of lwo. I have lightwave 7.5 and can't get my poser 5 to import a model I have created unless I save it as older version. Best to get the OBJ plugin for lightwave and save out of lightwave as an OBJ file. Poser really likes OBJ format much better than any of the other file formats that it supports or claims to. You can get the OBJ file plugin by doing a little digging at www.flay.com I think they have a link to it.
