Getting HPB values from matrix

    I frequently need to get the HOB rotation values from a matrix, and I don't like using the workaround of setting a dummy object's matrix with SetMg() then getting the HPB values with GetAbsRot().

    Does anyone have the formula handy? Thanks.

      mg = obj.GetMg()  
      rot = c4d.utils.MatrixToHPB(mg)  
      print rot  
    if __name__=='__main__':

    Ah, yes. How embarrassing. Forgot about that..

    Thank you, Scott.

    Thanks, Scott, for solving this issue 🙂

    Just a link for future readers, here's the docs of utils module, which contains quite a bunch of these little helpers.
