I’m having issues figuring out how to make an object which in sequence is attached to a path, and follows it from beginning of shot to end, at a constant rate/speed or velocity. It seems like the movement along the path starts out slowly and ramps up in speed and then slows down near the end. Even though I have two keyframes, one set at 0 for path start and 1 for path end. I would expect the speed of the object along the path to stay constant from beginning to end.
You need to change the interpolation type of the keys to Linear. Select the keys, right click and choose Linear. The keyframes will turn from circles to triangles.
If you prefer, you can set the default interpolation for your keys to Linear by clicking on the autokey button and choosing Linear.
Hey! i know im a few years too late, but this doens work for me my vehicle keeps speeding up and slowing down between keyframes depending on how far apart they are
