I would like the camera to follow an object. At frame 300 the camera should freeze at its current position and stop following.
I tried using Copy Location constraint (with offset) on the camera. At frame 299 is a keyframe with Influence 1 and at frame 300 is a keyframe with Influence 0. As a result, the camera jumps to its original position instead of staying in place. The same problem is with Child of constraint.
I also tried to use Transform driver for the camera with the object target. It makes a hard copy of the location (visible in Properties panel) during the animation. But I have no idea how to tell the driver to stop changing camera's location at frame 300 and leave these values as they are.
