Procedural Eye Shader - FREE! Download :)

Yes indeed UE4 now has a nice eye shader in the engine. In the Unity 5 version (Genesis Eyes) I chose to use a parallax style of shader so getting the cat eyes was really tough for just the pupils without stretching the sclera. I did get the glint and eye shine right though since it changes and moves with bright lights.

I like what you have done here. Well done indeed.
