Hello all.
I'm trying to align an object to a spline.
All works great as long as the spline's axis is aligned to it's parent's axis.

I know I'm missing something obvious, but if someone feels like nudging me in the right direction it would be much appreciated.

Here's what I've got:

  
vPosition = splineObj->GetSplinePoint(splinePos, 0, NULL);  
vTangent = splineObj->GetSplineTangent(splinePos, 0, NULL);  
  
m.off = vPosition;  
m.v3 = vTangent;  
m.v2 = Vector(0,1,0);  
m.v1 = m.v3 % m.v2;  
m.v2 = m.v3 % m.v1;  
  
op->SetMg(m);

Do "op->SetMg(splineObj->GetMg() * m)" to convert m, which is currently expressed in local coordinates of the spline, to world coordinates.
