I have a camera moving along a tube. It has two constraints: a Follow Path, and a Track To, in order to point to an Empty that is following the same path with an offset of frames (this Empty is also used as the DOF object).
The problem is that in order to keep the camera pointing “up”, the Track To constraint sometimes makes the camera rotate 180° in a non-continuously way, making the animation very nasty in those frames. I attach two screenshots that show the problem (frame 19 and frame 22), and the constraint configuration of the camera.
Thanks in advance!
