Poser is not very advanced when it comes to manipulating other kinds of objects than humans (and other creatures). Therefore you can safely assume that trees, skies, advanced props etc are created in other software packages and imported into Poser. I don't know if there are any rules about how much of the picture that has to be pure Poser in order to qualify it for the Poser gallery. My personal opinion is as follows: -The characters should be manipulated and posed in Poser. -The scenery should be set up in Poser, but may of course include imported props, background images and stuff from other sources. -The final pic should be rendered in Poser. -Post work can be done in PhotoShop or similar packages for the final touches. This is of course just my opinion. To have a firm rule that evrything must be pure Poser in the Poser gallery will seriously limit creativity. The simple reason is that there are things Poser is not very good at. No single software package can fulfil all the needs that a creative artist has.
