Cloth Pavillion Kangaroo 2

Hi,
I am planning a pavilion for a study project. With a wooden frame in the shape of a cube. A textile is to be stretched within this cube, like a kind of ball. It should look like the photo. I have fixed points on the rope and the ground and possibly on the wood where I want to clamp the textile.
In Kangaroo 2 I wanted to build a textile that I can move as freely as possible. I want to select and move anchor points. I also want to change the tension of my textile. In my current file, the “stuff” just sags.
Anyone have some tips?
I haven’t been able to find a suitable example yet.
