Guys, I'm making a map, but it includes those moving platforms. But here is the problem,which models are used for the rails and platform? Because I'm not going to use the Portal 1 models and the energy thingy.

Go into model browser and look up
arm
rail
platform.
Or if you want, you can decompile sp_a4_laser_platform, just to look at the models.

How do i decompile? sorry, im not the awesome type of mapper....
