SplineController Ignores Follow-Up and Chooses Wrong Spline
#4
Hi again,

I managed to get the necessary information from your package, thank you

The issue is that your controller basically behaves as if it's choosing a random spline when it reaches the connection. This is because the option you chose is "Follow-up otherwise random," but road_spline_01.CP0014 does not have a Follow-Up. In fact, it is road_spline_conection_3.CP0001 that has road_spline_01.CP0014 as a Follow-Up, and not the other way.

Feel free to read this documentation and watch the video tutorial at the same page to better understand Follow-Ups. For the sake of this conversation, just keep in mind that only a control point that is the start or end of an open spline can have a Follow-Up .

When the controller switches to the secondary spline, it basically switches to its last control point and automatically loops to its first control point, since your controller options allow that. 

This explains the behavior in your video.

Attached is an image of the configuration that allows the spline and the controller to switch to the secondary spline when reaching a connection.

About the update, I make a lot of effort in keeping all minor versions compatible, and introducing breaking changes only in change of major versions. But as an additional precaution, always backup your project before an update, and always read the release notes before installing an update.

I hope this helped.
Have a nice day.
