Yes, I have selected the option "rigid" to see, but that do the same torus with no deformation.

I see the easiness with "Flow" to do very incredible & complicated forms, and I trip over a simple Torus that doesn't want to bow like I want. That let me speechless.

If somebody arrives to bend well round, one torus on a half-sphere, I want to know the how of this miracle (lol).
