Off centre projection matrix breaks cascaded shadows

I have the same problem and I am using the PerspectiveOffCenter method found here http://unity3d.com/support/documentation/ScriptReference/Camera-projectionMatrix.html

Anyone have a solution?

I found a solution to this problem. You will need to calculate the aspect ratio and field of view before setting the new projection matrix.

Lets use the PerspectiveOffCenter example found here: http://docs.unity3d.com/Documentation/ScriptReference/Camera-projectionMatrix.html

And extend it with code to calculate and set the aspect ratio and field of view:

 using UnityEngine;
 using System.Collections;
 
 [ExecuteInEditMode]
 public class OffProjection : MonoBehaviour {
     public float left = -0.2F;
     public float right = 0.2F;
     public float top = 0.2F;
     public float bottom = -0.2F;
     
     void LateUpdate() {
         Camera cam = camera;
         float width = (right - left);
         float height = (top - bottom);
         cam.aspect = width/height;
         float fov = (Mathf.Atan(top/cam.nearClipPlane) - Mathf.Atan(bottom/cam.nearClipPlane)) * 57.2957795f;
         cam.fieldOfView = fov;
 
         Matrix4x4 m = PerspectiveOffCenter(left, right, bottom, top, cam.nearClipPlane, cam.farClipPlane);
         cam.projectionMatrix = m;
     }
     
     static Matrix4x4 PerspectiveOffCenter(float left, float right, float bottom, float top, float near, float far) {
         float x = 2.0F * near / (right - left);
         float y = 2.0F * near / (top - bottom);
         float a = (right + left) / (right - left);
         float b = (top + bottom) / (top - bottom);
         float c = -(far + near) / (far - near);
         float d = -(2.0F * far * near) / (far - near);
         float e = -1.0F;
         Matrix4x4 m = new Matrix4x4();
         m[0, 0] = x;
         m[0, 1] = 0;
         m[0, 2] = a;
         m[0, 3] = 0;
         m[1, 0] = 0;
         m[1, 1] = y;
         m[1, 2] = b;
         m[1, 3] = 0;
         m[2, 0] = 0;
         m[2, 1] = 0;
         m[2, 2] = c;
         m[2, 3] = d;
         m[3, 0] = 0;
         m[3, 1] = 0;
         m[3, 2] = e;
         m[3, 3] = 0;
         return m;
     }
 }
