I have built some pretty complicated rooms based on Geeps Magic cube (a 6 facet cube) as I think it is better to have seperate walls so then can be taken away like in a movie/TV room set. Also I like that using the cube you can see if your view is blocked as there are visible facets on each side. And since my base cube is a Poser foot cubed I can make a 1500 by 8 foot wall by scaling X=1500% y=800% and z=40%. I make component wall elements flush by setting them face down and dropping each part to ground... then I export the group as an .obj and import it back in and erect it into place... export and import again so it can be in place with the dials zeroed. I have done molding and double hung windows and panel doors (geep shows how to change the origin so doors swing properly). I import an open posed sliding window onto a close posed sliding window as a morph and I can slide it open and closed. The real pain in all this is using UVmapper Classic before assembling and while assembling parts so everything will map properly to a texture (using groups in construction is important for later in UVmapper). Geep explains all... Magic box, Poser "glue", the grouping tool. It is fun and worth the hassle for the satisfaction you get. I have seen on this forum such complex scenes, houses, chicken coops, temple structures, all done in Poser alone.
