Can not project points from one mesh to another

missing points.gh (35.2 KB)

I am trying to project a few points from A mesh to B. They have the same face and verts count. Not sure what is the problem, but there are some points missing in the B mesh at the edge positions. Please help me see the reason, Thanks!

Hello
logically you may do that, the P from Mesh Closest Point is a MeshPoint that is related to the input M (the mesh)

https://developer.rhino3d.com/api/rhinocommon/rhino.geometry.meshpoint

Or you can do that

But if I understand well you seek to make a sort of Mesh Map (Kangaroo or Nautilus)
BUT meshes MUST have same topology and they HAVE NO. Diagonal is 1-2 for one mesh and 0-3 for the other
