In XPresso you should pay attention to the order of the nodes in the X-Manager. The nodes should be arranged in the order in which they where calcultated.

In your scene it looks looks like this:

If the python nodes is moved to the end of the list...

...everything works as expected.

Hi,

I would use a BaseSelect to 'collect' all points of the neighboring polys. Deselect the first point and get all points without duplicates using BaseSelect.GetAll().

You don't have to compensate the position of the tangent, if you use

c4d.Matrix.MulV(self, v)

to transform the direction vector.

import c4d
from c4d import gui

def main():
    pointCount = op.GetPointCount()
    mat = c4d.utils.MatrixRotX(c4d.utils.DegToRad(45.0))
    for i in range(0,pointCount):
        
        point = op.GetPoint(i) #Point Vector
        point = point * mat
               
        tangent = op.GetTangent(i)
        vl = tangent['vl'] #Left Tangent Vector
        vr = tangent['vr'] #Right Tangent Vector
        
        vl = mat.MulV(vl)
        vr = mat.MulV(vr)
     
        op.SetPoint(i,point)
        op.SetTangent(i, vl, vr)        
        
    op.Message (c4d.MSG_UPDATE)
    c4d.EventAdd()

if __name__=='__main__':
    main()
