What I want to do is to render an animation where the rendered objects are not moving, but the camera is moving around them. OK for it.
But from that I want to use a hdri image in background which is also rendered.
My issue is the following: when the camera moves around the mesh objects I want to render, the background image is not 'synchronized' with the camera movement (and relatively to the rendered objects). The consequence is these rendered objects seem to move relatively to the background image.
Is it possible to avoid that? I'm thinking about camera tracking to compensate this unwanted effect. But is there a more simple way to do that? Or can camera tracking be a solution (if yes how)?
