What causes character controllers to sometimes fall through mesh colliders?

I have some static mesh colliders on which I move a character controller.

Most of the time it runs fine but every once in a while it falls through the collider it’s on.

Its skin width is 0.1, its radius is 0.18 and its height is 1.29. I’ve tried fidgiting these settings but nothing has made the falling through mesh thing go away completely.

What should I be looking for to reduce or hopefully get rid of this issue entirely? My game basically breaks when that happens so it’s a game breaking issue for me.

I see what you mean, I’t happened to me before. A main cause would be when you start your game and your player’s collider is penetrating through the collider it’s on. This will cause it to fall straight through.

Another way of putting it is if your player is a capsule with a capsule collider on it.When you start the game, Let’s just say 1/3 of the capsule is under the plane (which is the ground)that will mean the capsule will go straight through the whole plane.

To fix this, you need to make sure your player is not touching the ground at any point. You could even place it above the ground and let it fall and hit the ground when play is pressed.

I hope this helped :smiley:
