Extend object animation from another object

[yann19]

Hi everyone,

I would like some advice as I am trying to copy and extend the animation of an object from another object in which I am having trouble with.

I have a attached a simple scene, where there are 2 objects - ball01 and ball02.

• `ball01` has animation keyframe from 1-10 while, 
  
• `ball02` has animation keyframe from 10-20, with frame 10 of each object at the same position.
  

I tried using parentConstraint which seems to work but that would ends up `ball01` losing its initial animation from frame 1-10.

Any other ways that I can try out with?

Many thanks in advance for any advice!

Would like to add on another question that I have forgotten to mention - If my scene may or may not have animation layers... Will it affects such animation-extensions?

Hii all, any takes on this?

Sure. Use your parentconstraint. But bake off the keyframes : select>select key>bake animation. I recommend hilighting trans and rots in the channel box and using the ‘from channel box’ option. This will save the animation. Then delete the constraint. Shift the second object’s animation to start at the end of the first. Constrain again and bake the rest. Delete the constraint. 

Alternatively, python or mel using xform to match the positions in a range loop for one object’s anim, then the next range for the other....but seriously, just bake it 😉

Hi Simon, 

Thanks for getting back to me. I am a little confused about your solution, especially on the first constraint.

Do correct me if I am wrong..

`ball01` has animation keyframe from 1-10 while `ball02` has animation keyframe from 10-20 and I am trying to copy the frames from `ball02` to `ball01`.

In your method, you mentioned about baking the keys. So I have did that to `ball01` in which there exists a keyframe animation that ranges from 1-10. Going forward to do the first parentConstraint, I suppose it will be from `ball01` constraint to `ball02`? As soon as I did that, the initial animation on `ball01` will be gone..
