Question Control Track Preview On Cursor Hold Skips Frames: how to fix that?

Hi,

I'm really struggling to use properly the Timeline when the editor framerate is low and my timeline contains a lot of control tracks:

Whenever I move the cursor a tiny bit too fast, the state of a control track or of an animation is stuck to the last frame the cursor was on. This makes it very difficult to properly animate multiple control tracks because you are never sure if what you are watching will be the actual behaviour. Even just hitting the play button creates inconsistent behaviour.

It gets even worse when you go back and forward multiple times: the state of the tracks if completely lost, some tracks getting stuck in a state they would have a few seconds later.

A simple example: if you animate a full-screen black sprite to make a fade in fade out, scrolling through the clip will have you left with a half black screen until you manually scroll back to the start, and carefully and slowly try to go through the whole clip: this is not usable at all.

Is there a way to fix that? I tried to change the playback scrolling mode, but it didn't change anything.

Why isn't the last frame of a clip evaluated when the time is out of the clip? This would make the timeline much more usable and accurate.

 

That's unfortunate Any chance that this would change in the future?

Would it be possible to add "lock" track clips that hold the same keyframes until another clip overrides it? Without making any extrapolation, this would be enough to make them fully usable.

One important question then: If the frame rate of the game is low, does this mean that the state of the control track at the end of the clip is not guaranteed?

 

Thanks a lot for your answers!

So as a conclusion, I think relying more on animation tracks and using control tracks only on secondary visual elements sounds like a safer and more practical solution until this issue can be resolved.
