As far as I can tell, those allow you to import the figures, they may even rig the figures for you, but you have to animate using Lightwave's controls instead of using Poser's dials. That's one of the things I like best about poser - the dials. Oh wait, I just checked again and they have an "Animation Loader". It only works with Single Figure animations but...

Before they made me they broke the mold!
