The minimum contact penetration value in order to apply a penalty force (default 0.05). Must be positive.

This value is usually changed in Edit->Project Settings->Physics inspector instead of from scripts.

	Physics.minPenetrationForPenalty = 0.1;

using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour {
    void Example() {
        Physics.minPenetrationForPenalty = 0.1F;
    }
}

import UnityEngine
import System.Collections

public class Example(MonoBehaviour):

	def Example() as void:
		Physics.minPenetrationForPenalty = 0.1F
