I think panoramic renders in Vue 5 are the same as Longitude/Latitude images in HDRShop so you can: 1) render in Vue a Panoramic view (360) (in Render settings); 2) load the render in HDRShop and transform it (in Image>Panorama>Panoramic Transformation) from Latitude/Longitude to Light Probe; 3) use the Light Probe in a Poser 6 IBL. Yes, Poser 6 use LDR images only, not HDR, but you can apply the above transformation in HDRShop to LDR images too: it involves the geometry of image, not its lighting informations
