Is there a way of creating the illusion that a map is always moving by making the ground texture animated to move? Or at least have the floor BSP model constantly moving, then looping after a while? I tried it using a giant func_door, but the problem is that it always has to reverse back into position. It would be much better if I could the texture to just move in a linear direction at all times, but then objects on the ground will not move with it. Any ideas?
