I have tied a camera to an invisible box. Next I have tied the box to a path.
After adding key frames the camera inside the box moves through the path.
However, at some point of the animation, I would like the camera to "reverse". That is, I'd like the camera to follow the path as previous, but I'd like it to rotate to point to the other direction.
The illustration shows more precisely what I want to achieve. The camera circles around, rotates to point downward and goes up (zoom out from the plane).
Red - camera orientation
Black - camera movement
When I add a key frame on the box, or camera, Blender seems to ignore my settings. I suppose because box and camera are tied to the path.
