BB and here we got a problem with, the image provided above is not a mirror panorama image for sphere map , mirror don't mean flip it horizontal in this situation.. the image you have to provide for this test should be a L/L panoramic image converted from Light Probe or a mirror ball to work it correctly so it works in harmony with the Light probe light and the image from the inside sphere...
this way the image will look correctly inside and the scene would be lighted up correct too.. use the light probe from Poser7, convert to panoramic L/L map using HDRSHop map the sphere and see..
that what I am going to do tomorrow. provide a right material for the lightprobe and sphere.
