A wobbly antenna for a car

mojomajor

I have a car using some custom physics.
I want to add an antenna that is fixed at of the roof and wobbles around.
Kinda like a remote controlled beach buggy.

I tried so far:

a softbody3d pinned to the roof (looks amazing, but always falls down, since it uses global gravity settings and I can't override it)
a springbone3d with rigged weight painted mesh from blender, where I make the bottom bone stiff and less stiffyness when going up the bone chain (kinda works, but when going fast at a constant speed on a flat surface, it has a periodic glitch that looks unnatural)

The cylinder I'm using has 98 vertices.

Any other ideas?

Can you restrict physics to not affecting the Y axis? That should keep it from falling. Otherwise maybe you could reset the Y position back to its origin after each physics update (but that feels like a pretty bad hack and might result in other issues).

Maybe jiggle bone addon can help? Just invert?
