Vue terrain can be exported as an .obj and can be imported into Poser. Texturing then becomes the issue. A single image works, but variation would need to be painted.

My current feelings on this are that until Poser gets instancing there is little point in doing large outdoor scenes. I have never had good results from Terradome compared to Vue or Carrara, although that may just reflect a lack of skill on my part.

It's a bit of a race for me... if Poser gets instancing I'd dump Carrara (Carrara is easier to get Poser characters into and they preserve their functionality), but if Carrara got a morph brush like in Poser, AND dynamic cloth, I'd be happy to keep going with Carrara.I'd then consider investing in Octane so the renders from Poser and Carrara would look the same. ATM they don't quite.

You can't get a Carrara scene into Poser.

Oh, final thing... I haven't tried it, but Carrara can supposedly output to HDRI, so any Carrara scene could be used as an HDR map on the envirosphere as long as you set up the render that way. Something else I've considered as it would let me have image maps for different times of day.
