Thanks for the pointers so far ! I have a few more questions / comments which I hope people can help with ...

The obj file of the room is actually created by a program I have written. In theory I should be able to come up with something more appropriate for use in Poser. However, I am not sure what file format would be best to use. Certainly the obj file format has too many limitations. It also sounds like props might not give me enough control either ...

Given the above, what would people suggest as an approch ? What would be the best type of Poser object to create, a prop or something more complex (are they termed figures). I am certainly prepared to contemplate producing a hierachy file - can anyone point me to some documentation regarding their syntax / structure ? Does curious labs produce any documents for developers ?

BTW I have attached an image of a room that I have textured and rendered in Cinema 4D. If only it looked like that in Poser ... oh well.
