Double-sided shader with shader-graph

Question

I'm a complete beginner when it comes to shaders, I'm building a project and I need to use Shader Graph in it.

I would like to know if it is possible to render two different things on each side of a face, for example in the normal side render the texture and the normal maps and in the back of the face render a pure black without shadows or lights.

If you want to set your shader, made by ShaderGraph to render in Two Side mode, you have to enable this option in Master Settings like on the screen:

I don't want to just show the back face, I want it to show as pure black, no textures, no lights, no shadow and no reflection, just a solid black color – Renan Klehm Feb 13 '20 at 11:13

Then you probably need option "is front side". https://forum.unity.com/threads/shadergraph-make-shader-lit-on-one-side-unlit-on-other.607015/ – selezen88 Feb 13 '20 at 11:54

For anyone looking for similar on a newer version, it's under the Graph Settings tab inside of Graph Inspector.

Every answer I found was like above, click the cog, which isn't available on mine.

Well... I kind of figured a way to do it, I think that this isn't optimized at all, but it works flawlessly.

In the inspector I added a second material to the object and I created a new shader using the "Is Front Face" and the "Branch" node to set the normal faces transparent and the "back faces" to show the color I wanted
