Hi Guys, I'm new to this Forum.

I'm tryng to constrain an object to a point of a selected spline (animated with spline dynamics). I tried to use "camera dependent" option or "Frame Dependent" option, but doesn't work for me.
The real problem is when I render the scene and there is always a delay between the object and the target point.

Here my code

import c4d

def main() :
    obj = op.GetObject()
    Tag = obj.GetFirstTag()
    Spline = Tag[c4d.ID_USERDATA, 2] #the spline
    SplineObj = c4d.utils.SplineHelp()
    SplineObj.InitSpline(Spline)
    pointpos = SplineObj.GetPos(10,0)
    obj.SetAbsPos(pointpos)
    obj.Message(c4d.MSG_UPDATE)

If anyone has any tips or has done something like this, I would appreciate any advice or direction.
Thanks,
Luther
