I have had problems with this in the past. I’m trying to move multiple actors using the one matinee.
When I use “Movement Track”, everything zaps to one place with all meshes on top of each other.
When I use “Add Vector Property Track”, which worked in the past, it’s making several of the meshes change size and position.
Any help?
To give a better idea of what I’m doing, I’m hanging swinging hooks from chains from the roof. I was intending on doing this through matinee because I was struggling to use physics / wind etc. to do it, so if anyone has another way to simulate a chain swinging from a roof, that’ll work too 
Just in case this posts up on google for anyone;
How I solved this was creating a movement track for the first hook, setting everything up, then creating a movement track for the second hook and copying in the keyframes from the first. The problem was that I had to make some changes to the location of the position of the chain with the axis’ on each of the keyframes since I didn’t want them to all be on top of each other.
It was fairly tedious but unlike UDK, I didn’t think I was just able to plug lots of meshes into the one matinee. Perhaps theres a way but I wasn’t able to discover what it was.
The Add Vector Property Track option worked for me in the past because I was scaling meshes, not moving them. I have found that it only works in the instance of scaling.
My guess would be the easiest way would be to parent/group all the meshes together, then use just the one main mesh for controlling movement. 
That should work without requiring any extra tracks or keyframes.
