I have successful used "SplineController" javascript.
But I don't want to conncet the head and tail into a circle.
I makee a roller coaster.
I want camera follow roller coaster's path.
But "SplineController" let roller coaster's head and tail around a circle.
Like attachment, part of white line is superfluous.
I don't want this line.
What can I do? I think the question is in "SplineController".
Thanks everyone.
