Actually Ari he's referring to the Movers not moving models.
Yes you can make Mover's like that found in HL's intro train. I'm not sure if you can get it to that much in one shot but it can't hurt to try. Here's what you do...
First make sure the red brush is at the normal scale, so quickly reset the scale (this plays a role later so it's important).
Next subtract a section of the map that isn't part of the regular map. You're gonna use it as a building area.
Then simply create the shape of the Mover there.
Then when it's done, rebuild the map, click on the subtraction brush that encompasses the soon-to-mover shape, right-click=>Copy to=>Copy to brush.
Then click on the intersection button.
Now you've got the right shape with the red brush. Then click on the Add Mover button.
Simply add all the Keyframes to the desired place. One note, all the Keyframes are initially set in the same spot as Keyframe 0 so everytime you change it to a new Keyframe it'll be back at the origin.
And the final trick to making sure all of this works in the end. Go into the Mover's properties=>Mover=>NumKey setting needs to be set to the number of Keyframes that are being used.
Yes there is a limit keyframes, technically 8 for any specific Mover. That also adds the first Keyframe, something you should also keep in mind when you're determining the NumKey setting.
