When I want to make an animation with a camera in the motion study, I create a sketch and therefore indicate 2 points (start, arrive) to the camera. But when I do the math and then the reading, my camera rotates on itself. I've tried a few times and usually, it starts straight, and it ends upside down.
I checked directed on the target, and my camera remains well pointed on it. Just that during the journey, it pivots. I tried the same way as the tutorial given but still the same problem.
