I am working on an older file with a background image. In the animation, the camera moves and pans relative to two objects in the scene. But the background image behind the camera and behind the objects looks the same at every point: The background image is not effected by the move/pan.
I know this solution for Cycles: Add a panoramic background to scene in Cycles
and it performs (in cycles) as I expect: the background image changes as the camera moves/pans... I am unable to recreate this in BI... and clearly I have forgotten something.
All input welcome.
