Smart Rail Generator

In Cinema4D when dealing with Sweep NURBS, or Spline Wrap, or even cloning instances over animated splines it's very common case when object twists around a spline — either in certain areas, either in-between frames.

Here's Smart Rail genertor comes handy — it produces rail spline which resolves twists along spline, and keeps stable orientation during the animation.
