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?

Hi, is there a way to define in VOPs your own coordinate space for point? Say I would like to state local point coordinates where z is point normal, x is a tangent to zet and y is a cross product of former two. How can I do that? I need it as a sop op, to describe the motion in local point coordinates but not in world coordinates.
Thanks

hi
is there a way to create an expression which would tell point of wan sop to snap to a closest point on another sop with specific atribute?Like look for closes poin which is black and snap to it.
Thx

Hi,
why I'm not able to trnsfer attributes from popnet to point sop?
Say, I have a box, append to that pop net, there I put source and append attribute. In attribute I say ad to tx value 0.1 every frame. Back in sop editor I append point sop to that and try to read values to point tx attribute, but nothing happens. If I append point sop to original box sop, and wire popnet as a second input in point sop and write $TX2 for translation , getting error messages.
What am I doing wrong?
