The anatomy of this setup goes like:
- Box: Sadly still RBD doesn't interact quite well with vellum so I had to fake the rigidity of the box by using Struts constraint with some stiffness,
- Wires: I went with the hair constraints since I can control the bend.
- Cloth: I had to create a custom force to stop it from collapsing and to give that air resistance feel.
It was a bit tedious to achieve this balance between (size, density, stretch, bend, forces …..)
