How could I know that the maxStepHeight in PhysicsCharacterController works as expected?

In this pg, I can’t see any difference when I changed the maxStepHeight value. Anyone knows?

Making it extra small prevents you to go up the stairs. https://playground.babylonjs.com/#WO0H1U#210

What about the bigger value? Why can’t I walk over the higher steps？It seems something restricted

I got it ! The maxSlopeCosine should be small enough and then the maxStepHeight would work as expected.
