How can I animate a library object?

[woosh]

Usually animating objects from the library works without problems.

For me animating the oldCar from the library works just fine.

A few ideas:
- are you using the cyclic modifier?
- is the model linked correctly?
- are the keyframes set correctly?

Besides that I'm not sure what the cause could be, if you want you can share a screenshot or your .blend file, that might help to find the issue.

You're right, the animation happened faster than I realized and it wasn't cyclic. Thank you!!
