Shaper is an add-on that provides functionality similar to the Transfer Attributes tool in Maya, specifically designed to support workflows involving Marvelous Designer. It offers two primary operations for manipulating mesh data. The first operation transfers a UV map from a selected object to the active object based on their shared 3D space. The second operation snaps the vertices of the selected object to the surface of the active object using their shared UV space. The tool also includes options to automatically merge doubled vertices and smooth the resulting topology after the snapping process is complete.
