Keyframes improperly affecting animation
This is a tricky one, but I’ll try to describe.
WHAT I’M TRYING TO DO
I have two robotic arms picking up one object each, then moving them to another place and dropping them.
HOW I’M DOING THIS
I have X and Z position keyframes on both of them, which I turned into “soft” so I could drag the motion path in the viewport. I’m also using the “time” special keyframe to ease this motion (this could be my mistake).
THE PROBLEM
Let’s say I’m moving the robotic arms with three sets of X and Z keyframes:
- Set 1 -> Set 2: Move the robotic arms above the objects
- Set 2 -> Set 3: Hold for a second or two
- Set 3 -> Set 4: Move to the next location
For some reason, when I drag the first set of keyframes earlier, it impacts the position of the arms even after the third set of keyframes. Why could this be happening? BTW I have a constraint tag on the objects these arms are grabbing so that they follow the nulls of the ends of the robotic arms during Set 3 -> Set 4.
If it would help, I’m happy to share my project file and a video of the issue.
Thanks 🙂

Hi Matt,
This may be related to the Constraint tag, however, sharing the file and the video would be more helpful as you stated.

You are welcome, Matt! I think as you previously expected the reason for the set of keyframes being linked is the “time” usage, I deleted it and the linkage was gone as in the screen recording, also I didn’t notice any change in the arm movement after deleting, let me know if this works for you

Ah nice. Do you know if there’s a way for me to still smooth the timing of the animation without breaking it with the time keyframes?

There are other methods, but they may differ from the principle on which your animation was built, so you cannot apply them now, such as using an Effector for example. I am not familiar with the “Time” tracker, but it may help to making the time entry the last thing you do after making sure that you have made all the changes you may need it. I hope this is useful to you.
