You can use it on whatever polygon you choose. In order for Lightwave to export your uvmaps with the obj, you have first to assign your materials: in the material editor choose the material, assign uv mapping in the type, choose the name of the uv map you made, then save the LW object. Export your obj and the uv information will be there. They will import just fine in Poser, not only that but you can have multiple uv maps for one object the same as the Millenium People.
