DrawFrustum not the same as camera

Question

Hi,

I've been trying to draw a frustrum of a camera point. I've been using Gizmos.DrawFrustrum(...) yet for some reason it doesn't match the gizmo of the camera. I can't find what I'm doing wrong, so hopefully someone here knows.

Here's my code:

     Gizmos.matrix = Matrix4x4.TRS(
         Camera.main.transform.position,
         Camera.main.transform.rotation,
         Vector3.one);
     
     Gizmos.DrawFrustum(
         Vector3.zero,
         Camera.main.fieldOfView,
         Camera.main.farClipPlane,
         Camera.main.nearClipPlane,
         Camera.main.aspect );

And this is what it looks like: alt text

If I change the aspect ratio of the camera, the frustum does not change. For some reason the Camera.main.aspect is always 1.3333 and I don't have a clue why.

Any help would be appreciated!

Thanks

There are a couple of other threads that people have replied with solutions for drawing it yourself. It would just be nice if this was a silly gotcha that was easy to get around.

Here is a link to one such solution for the next guy that comes around: http://forum.unity3d.com/threads/drawfrustum-is-drawing-incorrectly.208081/
