Quote - for whoever said this:

bring in the characters as well via Body Studio <<<<
and anyone else who thinks that's what Body Studio (before or after being bought by EF) does.

IT IS ONLY HOSTING. Once you get your scene into Max, Maya or Cinema you will not be able to move anything. No morphing or adjusting. NOTHING NADA.

Good point on the PSA Opera, but I wasn't concerned at this point about being able to bring fully-rigged characters into LW. I'll just be happy with hosting--it will give me access to LW's renderer for animations.

I'll want to have fully rigged characters imported into LW at a later date. For now, hosting is sufficient for a project I have in mind.
On a side topic. whether or not Poser will create an effective character importer into LW or any other 3D app is likely to be a point of contention. Poser's content library has Poser or Poser Pro as a gateway. Write a means of importing Poser content into LW, and what do you need Poser for?
