Add Mesh to vertex keys

Hi!

I work on an animtion with vertex keys and I have allready five keys.
Now I want to add some meshes to all the keys at the same position. AND I want to scale and rotate these meshes! But when I do this, the meshes scale and rotate to their starting position at the other keys.
How can I scale and rotate for all the keys at the same time?
Thanks
Markus

It is not very clear what you intend. Do you want to make a change in geometry in one key and then propagate this change to all other keys?

If that is what you want, I posted a small tutorial which might (or not) be adapted to your case.

This tutorial says:
An important thing to note is that your mesh should be in its final state. If you add or delete any vertices after adding RVKs you will likely have to reprogram them all. So make sure you’re done making the mesh. All we’re going to do from here on out is move vertices around.

But my mesh wasnt in its final state! But I did it without reprogramming!
I duplicated the meshes, and then I could scale and rotate them for all the keys. I added some eyes and they are at all the keys at the same position.
Thanks for your fast answer tolobán!
