issues with face over lapping and generator ranges

[_Aka_]

But I was wondering can i make same thing Spline to Mesh at runtime from code.

Yes you can. here is the code for it. I will include this code in an upcoming update:

Code:

public static Mesh SplineToMesh(CurvySpline spline)
    {
        Mesh result;

        Spline2Mesh splineToMesh = new Spline2Mesh();
        splineToMesh.Lines.Add(new SplinePolyLine(spline));
        splineToMesh.Winding = WindingRule.EvenOdd;
        splineToMesh.Apply(out result);

        if (String.IsNullOrEmpty(splineToMesh.Error) == false)
            Debug.Log(splineToMesh.Error);

        return result;
    }
