If the IBL image is matched to the background of the EnvSphere do i need to make a new IBL image everytime i move or rotate the camera, or does poser take this into account and the IBL is rotated also to give a correct lighting in the scene...ie.... if i do and animation of a camera rotating round a person will the light from the IBL follow the camera or stay stationary so that it is locked to the lights position?????

Getting old and still making "art" without soiling myself, now that's success.
