The issue is that these verticies are already pinned. there is no seam in the low poly version, and the high poly has the same number of verticies along that seam, so theres no reason they should stray.
However the calculation doesn't seem to account for being in exactly the same position as one of the members of the base triangle. I need to make a modification to the proxy script which detects if the start slave vertex is in the same position as a master vertex, or perhaps a pinned particle, then bypasses any normal, tangent and position calculations if this is the case.
How would compare the two in the script? is firstVertex the closest vert to the slave vert? How do i get the origional slave vert position?
