Now this would probably only work in the case of a tube with exact portaling, but would it be possible to make grav lifts sync for tubes, at least, by making an area with reverse gravity effects? If this could be accomplished, you simply would move upward due to gravity and then when you came out the end, your momentum would keep you going fast enough to bounce off a playerclip and to the floor to the side. Anyway, I need some opinions if this could be done. Anyone with experience in portaling and gravity perhaps got an opinion.
