How do I make a twisted wrapper like the following?

Enter image description here

I've tried to twist a plane / a cone, but many faces just go though others.

    Apologies if this is obvious or not relevant, but if it's for a piece of candy, the twists on each end go in opposite directions so it opens when you pull. Yum. – bmb Nov 07 '19 at 19:44

If you want to use the cloth simulation, you have to assign both ends to bones.

bone influence

You also have to create the Pinning group for the cloth simulation. At the pinched end, I used only a few vertices for pinning, otherwise the circular structure will remain rigid.

Animate the right hand bone twisting.

This is the result with a cloth simulation.

Leander has given a nice solution with Cloth physics, here are solutions with modeling only, you can give them Cloth physics at the end if you want to make it more realistic.

  • A bezier curve to which you give a bevel object and a taper object. If you select the bezier vertices you can twist them with CtrlT, AltT to reset, N panel > Transform > Tilt to type a value.

  • A tube mesh to which you give a Mesh Deform modifier. Create a cube that encages it, choose it as the Mesh Deform object, create a basic shapekey, then a new one that you twist the way you want (no risk of face intersections with this method).

  • If you give it a Cloth physic afterwards (here Leather).
