Is there some sort of "minimum length" for a single track piece? They seem to want to fold into themselves if they get too close.
If they fold, highlight the vertex point and pull the bar in towards the center point. Then the track will continue to the next peice less far and they won't fold.
Yeah...I figured that might work too. All it did (for me) was just make the fold/flip/twist in the track more abrupt. Of course I don't know how close I had it, but I'll keep trying.
Try rotating the last vertex you put on the track. Sometimes it is placed rotated around in strange places, I believe the amount of rotation depends on how long the control arm of the previous vertex is.
