This is taken from a roller coaster that I've actually designed in No 
Limits.  The problem with using the fact that No Limits uses beziers 
becomes apparent in a couple sections, where the track has a significant 
jerk in it, as the radius of curvature doesn't match on each side of a 
bezier control point.  The direction is the same, but a sudden change in 
the speed of change of direction creates the jerking.

Render time was 18 hours, 14 minutes total, with 7 hours 13 minutes of 
that time being spent parsing.

The next version should parse faster as track tie (And possibly 
sphere_sweep data) locations will be calculated only on the first frame, 
and may include a complete coaster with banking, though still no support 
structure.

ETA: About a week, perhaps.  I'm working a lot these next few days.

Uugh...  Makes me feel ill to watch it.  (In a good way.)

Good work.
