Im looking for a walkway, similar to the one in the shown below, but in a more TF2 style. In addition to that, I would like a separate prop that could be added on to the end of the walkway, to make it look like the end has collapsed. If anyone can do this, I would be very grateful. Also: Please ignore the mind-numbingly bad quality of the pic, it's a screenshot from a video off of YouTube, since I don't actually own Portal. EDIT: On second thought, I really only need the end of the walkway, since there are railings provided and it only takes one brush to make a normal walkway.
