In the user manual (2.83), the character controller is mentioned and it's pretty cool to have that working out of the box.
However, it took me many attempts of falling through the ground unitl I figured out that a btGhostPairCallback has to be registered manually on the broadphase for any of this to work. As far as I know, there is no documentation or example for this controller at all. The way I figured it out, was by recognizing that btGhostPairCallback is not referenced anywhere in the bullet source code.
