Jump over a box (need to be in a corner) of the box then crouch and uncrouch at uncrouch the capsule of the player change the size, and all bounces:

Hey Hevedy,

I believe what you are seeing here is just a quirk of PhysX.

What is happening is the bottom of the capsule is rounded, so when you are on the edge of the box you are close to sliding off.

So when you crouch/uncrouch there is some ‘slippage’ that registers the hit on the physics box.

You can test this, and also fix the issue, by going into the FirstPersonCharacter > CharacterMovement component > Details panel > Character Movement: Walking > and Enable ‘Use Flat Base for Floor Checks’.

Let me know if this will work for you.

Cheers,

TJ

Nope my friend, I think even in the uploaded project the Use Flat is set and give even more problem in some cases and don’t work properly in sides because fall as the rounded one.
