The thing is that when I pass a different value for X or Z, the cylinder doesn't scale properly and it is really short, when it should be larger in the Z or X part, and smaller on the other axis.
What would be the best way to implement this? I can't use a btBoxShape because some platforms are very big.
Here is an image (bottom-right is a cylinder with the same radius, and top-left is platform with different radius in the X and Z axis):
