Shape Transfer is a tool for transferring shape keys between objects, primarily used to conform clothing to character body morphs. It copies selected shape keys from a source mesh to a target mesh without overwriting the target's existing shape keys. The add-on automatically configures drivers, allowing the source object's shape key sliders to control the corresponding shapes on the target mesh in real-time. To ensure successful transfers, the source mesh must follow specific topological guidelines, such as avoiding non-manifold edges, overlapping vertices, and collinear edges. If a binding fails due to concave geometry, the add-on will automatically attempt a second transfer using a triangulated version of the mesh.
