Why was this removed?
For those that don’t know: in older versions of blender 2.5 you could tell the mesh deform modifier to use surface mode. This made it so that the deforming mesh did not have to enclose the mesh being deformed. The main use for this was to create a cloth sim and then tie it to a high res mesh that included things that wouldn’t have worked in the sim such as cuff links or buttons.
Also, does anyone know an easy way to replicate this functionality in current versions of blender?
