"I know that Inspire has oficially dead for some time now, but are there any other people out there still using it?"
Yeah, Inspire is pretty "dead" now. It's a shame. It was such a great little app. I would have thought that Newtek would have wanted to latch onto the entry-level people.
Inspire was my real first step into "serious" 3D stuff. I've since moved up to LightWave (v6, then v7.5c), so my copy of Inspire doesn't get installed any more.
Like the other poster said, most of the .lwo models that you'll find on the web will be in the later (v6+ or v7+) format. You can sometimes import these objects, but you'll lose the texturing data, since the later versions of the .lwo format allow for UV mapping data and (LightWave-specific) texturing plugins that Inspire doesn't have.
