I still had the 'Meatless Mike' scene loaded when I noticed free...

... ported by kanbara914. In addition to XPS-types 'generic_item.mesh' and 'unconverted_mesh.ascii', there was an FBX file.
"Shall We Tag-Team Him ?"
Yuffie FBX slowly imports to Poser at ~100% original scale as a bunch of named sub-rigs. Parent these to a dummy place-holder to move figure. Pose within wary limits by selecting limb from hierarchy, not by clicking on limb on screen. Poser TGA texture transparency may default to ~85%, so figure appears translucent, 'glassy'. Dialling each back to 0% solves that. Also, edit default diffuse base-hue from green (!!) to beige...
FWIW, if porting to eg OBJ and a whatsit_mesh.ascii is flagged as invalid by eg ($$) 3DOC, try renaming it to whatsit.mesh.ascii
I don't reckon this scene is good enough to 'stand alone'. Poser seems to have lost too much of the texture info, while complaining about shortage of memory. Yuffie's 'rig' came apart into a 'bakers dozen' named sub-rigs: armor belt, head, eyes,tassels, pant zip, hair, eyelashes, eyebrows, clothes, armor, pants, body and mouth. Each with a complete figure hierarchy. Poser's hierarchy window really struggled, I kept expecting a crash...
Floor texture is not a 'render artefact', I set it to Poser's own 'Blue Veined Marble'
