Newton Help

I would want to know on how to make a turn off the end of a hill when it is going down but to come back up.
Example: http://www.coastercrazy.com/track_exchange/detail/18153
On the second drop it seems to turn and it does it so smoothly, but can anyone tell me how to make a good one.

Not sure that track is a particularly great example of the element you mean (the transition feels too abrupt for me) but I can tell you how I make mine (did it a couple of times on Omega) if thats any help.

Roughly speaking, after the hill crest I have the normal transition reach a constant value about 1/2 - 3/4 of the way through the element, with a very negative centre. The roll is zero for a very short time, then transitions to the necessary value again with a negative centre.

This should give you the basic shape, but obviously depends alot on your initial conditions and will take plenty more tweaking to get it right.
