Edward,

my goal is to transfer motion from one geometryn to another. Although they have the same topology, thay different geometry, therefore motion vector for each point has to be reoriented. As far as I can figure it out, the best way is to compute rotation matrixes using normals as one orientation reference and one of connected to point edge as another orientation reference.Then using AlignOP I can get rotation matrixes to recompute motion vector.

Is there a way in point sop to set the up vector attribute to be oriented along one of the connected edges, specificly along the edge going to point with the smallest ID nr?

Thanks MatrixNAN, will try it.
