Some times mesh distortion.

Hi, sorry aka because my carelessness.
I checked it carefully again. It seems like it is the case

---

"This is probably because it is a Bézier spline, and the Bézier handle at the first CP is very long while the one at the second CP is very short."

---

This problem occurs because the position of 3 CP is so different. Although there are many segments like this on the whole game but usually will only be in 1 -2 segments.
Is there any way to fix this problem? . My game is music game and requires the position of the points to be accurate, so stretching the distance between points is can't.
I tried checking how CP works. But I don't understand anything.

I use this code to creat cp point ( edit from InfinitieTrack)

           

---

           Vector3 p = TrackSpline.ControlPointsList[TrackSpline.ControlPointCount - 1].transform.localPosition;
           Vector3 position = TrackSpline.transform.localToWorldMatrix.MultiplyPoint3x4(p + mDir * CPStepSize);

           float rndX = valueCurX;
           totalCurvationX += rndX;
           float rndY = CurvationY * RoadDefine;


           mDir = Quaternion.Euler(rndX, rndY, 0) * mDir;

           //Skip Fist node spline
           if (TrackSpline.ControlPointCount > 1) CreatRingAndAddNode(position);
           CurvySplineSegment newControlPoint = TrackSpline.InsertAfter(null, position, true);

rndX allway to be 0. rndY random 0-10. CPStepSize calculate follow time between node of song.
