I tried the bend tool and simple bend modifier with no success because it didn't give me enough control on the bend trajectory, I then tried the bezier curve modifier, I applied a bend on the X Axis, to have the wrist part curve, then a second bend on the Z axis to have the top part curve down too.
My problem is that I want the top part to be flat on the X Axis, because after a 180° Z Bend, the top part of the object now moves away from the X Bend trajectory, as it is now mirrored.
I tried applying Vertex groups on the bottom half so that the top wouldn't bend on the X Axis, but blender doesn't make a smooth transition between flat and bent parts, I get weird connection polys instead of a fluid twist (or untwist in this case).
Is there any simple way to bend an object in two different directions ? A bit like so https://blenderartists.org/t/c4d-like-bend-deformer/1146668
