ya can't. not as lwo. if you have lightwave you can export the model as an obj and then import into poser 5, or you can use a converter that will read the lw 6 /7 model and convert it. I think the older DeepUV will do that, there is a free version before right hemesphere bought it that you can use, but I don't have the link anymore sorry. basically if you want anything into poser 5 obj files are the way to go
