Hi Emre,

Call up a Null, while the Null must sit in the center (position zero, rotation zero, Scale 1.). Then place all your objects under the Null.

Now you can move the Null and, if needed, set keyframes to that Null.

Let me know if that works for you. If you can, share a c4d file, which can be an example file, so I can see what you have done and suggest the best practice. Just in case the workflow above isn't working,

My best wishes for your project.
