I created a procedurally-generated cityscape inside Blender.  I used 3 different creator's city generation scripts.  The one in my example is Piiichan's Suicidator City Generator script.

I exported the mesh as OBJ. I created a Box UV material inside UVMapper.  I re-saved the OBJ.

I imported the OBJ into Poser 7

I created a randomly-generated base texture with B D Tibbett's city_gen texture generator application.  I included this as part of a shader I devised for city night-lights effect in Materials Room of Poser.

Results as shown.

Because of the many variations in cityscape and texturing possible, a wide variety of cityscapes may be created for use as Poser backgrounds.
