Toon Shader

Hi everyone!

I’m trying to make a toon shader, but this is a fail…
This is the rendering of my level with my Toon Shader

I use a post processing volume, and like you can see, there is a strange lighting and I have a black sky!
I give you my material

You can [download][3] here my toon shader
I already try to see if people have made this, and yes, [here][4] But, I don’t know why, I don’t have the same things.

Thanks to help me.
