Hi everybody, and thanks for your experiments.

Like I said in the french section, I try the demo with a "simple" shape, but not easy in the reality.
I don't understand how to arrive to a smooth shape. I tried different methods, but not great in the render.

I have created a new scene with clean shapes (in the attachments), and a fast test in cinema 4d to see the form which i like to arrive :




Thanks.
