Remarks
You can not invert matrices with a determinant of zero.
using UnityEngine;public class ExampleScript : MonoBehaviour{ void Update() { // create a transformation matrix with scale, zero position and no rotation var scale = new Vector3(5,3,2); var matrix = Matrix4x4.TRS(Vector3.zero, Quaternion.identity, scale); // determinant of a scaled matrix is volume of the parallelepiped // formed from its axes, in this case 5*3*2=30 Debug.Log(matrix.determinant); }}
See Determinant on Wikipedia for more details.
