Sorry for any typos, typed on phone: To avoid any further confusion I think the matrix you're trying to build is the Vertex' tangent-space matrix.
These are per-vertex as opposed to per object like he local matrix. So what you'd do is retrieve the "delta" in tangent-space of and re-apply that delta on the other mesh. Note that a Vertex' position multiplied by its own inverse matrix would always be zero since its tangent-space matrix is based on its own position. What I think you're trying to do is create Tangent-space blendshapes. Basically you create the delta by having two meshes and store the delta: delta = blendshapePt * tangentSpace.inverse() And then apply that delta to another mesh's point in that vertex' tangent space: targetPt += delta * targetTangentSpace Not sure about the order of matrix multiplication here, I always tend to mess it up in Maya when doing it out the top of my head.
