Sequencer Keyframe lerp Bugg

Found this issue in a project im working on and was able to reproduce it in a clean project, link below.

If you have a level sequencer with camera cuts etc with multiple keyframes, the lerp for the camera between the keyframes changes if you move the last keyframe.
As you can see in the video, i have 4 keyframes where the camera moves between them, at first they move perfectly as intended, if i move a keyframe in between (not the last one), they still move as intended. But if i move the last one, the lerp to the Second to last keyframes is different, it moves, then freezes for a little bit, then continues to the last keyframe. This happens, even if you move the last keyframe, then move it back to where it was.

PS. dont you get any karma for reporting bugs? This stuff takes some time xD

Hi nameLive,

In your project, the 4th key is set to have broken tangents (see the curve editor). I am assuming that you copy/pasted the first key, which breaks tangents on the keys around it so as to not mess up their interpolation with the other keys.

Broken tangents will cause those harsh transforms those harsh transforms. You can simply select your 4th key(s) and set Cubic (Auto) interpolation again.

Hi, i did not copy paste the first key but by pressing Cubic on the last key it fixed the interpolation and made it smooth again, this is going to save me some headache. :slight_smile:

Thanks!

Glad to hear it. Whenever something weird like this happens, turn to the curve editor to see what’s going on there.
