This is why I still use Poser Pro Pack (and Lightwave 6.5). I don't want to have to rig/weight map. I love the Poser dials for animating. The Lightwave Import plugin that comes with ProPack allows me to do just that. If the only reason you're interested in Lightwave is to be able to interact with your Poser scenes (at a higher quality) there are other options. Wolf359 has had good success with Cararra. If I were to start now that's what I'd probably use. It's a direct import of Poser scenes into a quality renderer (and animation and modeling app). He's a Lightwave user as well. Shade, made by E-Frontier, also appears to be able to import Poser scenes directly. There's a free demo download available at E-Frontier's web site. Both of these are less expensive than Lightwave. Please don't take this as a slam against Lightwave. I like it a lot. However, these are viable options worthy of consideration both for budgetary and quality reasons. I know what it's like to not be able to afford things. All too well...

Before they made me they broke the mold!
