Curve merged but weird twist happens? So I'm making a track for my car to ride over and I've been working with curve tilt. This weird twist shows up at the point where I merge the ends of the curve together. I already tried to remove the segment and remerge (if that's a word) it. Doesn't work.
Any ideas?

I already made it cyclic and I started tilting it but of some reason It does this even when redoing the merge. There is a full twist somewhere else on the track so that is probably a reason.
Make sure that in the Global Transforms the segments have the same tilt:

When two segments have different tilt (90 and -90) you'll get a loop when you connect:



Wehn the segments have the same tilt, the segment will be straight:



If one of your segments is flipped try this:

Deselect all (A)

Select one control point and then select linked (L)

Rotate the whole segment 180 degrees by adding +180 on the Mean Tilt section.

Link it then with the other section.
