This is a very weird script. It erases the symbols inside the resource manager.
The primary idea of the script was to design frames of different shapes straight from the size of the picture image using multiple symbols for base. This is not possible in VW because of the way symbols are packed.
Marionette is THE solution. I started from a normal script based on size of the image, a shape and path extrude. It woks fine but you cannot have a library of shapes (see script picture).
