Is there a possibility to build such a film. It should be two superimposed films. The lower straight and the upper arched upwards (see the attached picts).
Such shapes are not (yet) supported. You can try to use curved images for that, but I don't think they will work the way you need. Another option is to find such shape somewhere else and load it as external model.
I'll move this to the "Ideas" category, see if it gets enough support, so we can consider adding this shape.
