Since upgrading to Unity 5.2.3 the below shader renders my object completely black.
http://wiki.unity3d.com/index.php/Silhouette-Outlined_Diffuse
My knowledge on shaders is not great, which is why I looked to the wiki.
I have tested this on Unity 5.2.3 and 5.3.0 with the same results.
Any help would be much appreciated
