Weight Subdivision Surface
This page covers the Weight Subdivision Surface tool in Cinema 4D. By dragging on points, edges or polygons of a Subdivision Surface child, it paints weights that locally sharpen or soften the subdivided result — stored in an SDS Weight tag.
You can weight Subdivision Surface objects using this tool. In order to do so the Subdivision Surfaces’ child object must be edited. Active points, edges or polygons can be weighted by pressing the left mouse button and dragging the mouse. If not already present a Subdivision Surface Weight tag will be created in which the weighting for each element will be saved.
For information on how to use the tool, look up Subdivision Surface object.
