    Hello,

    I have a very simple shader in Unreal 5 and i try to achieve the same effect in Unity. My knowledge of shader is very limited and i dont know all subtility of Unity and it workflow.

    This is the effect i want reproduce :
    TwoSidedSign.png

    it's working in any direction, without pass any parameter to the shader.

    According the UE doc :
    The TwoSidedSign expression is useful for flipping the normal on backfaces of two sided custom lighting materials to match the functionality of Phong. +1 for frontfaces, -1 for backfaces of a twosided material.

    I have read some threads about fliping normal on backface, but two things... One, i dont understand the quarter of what i've read, second, what i've understanding tell me is not fit my need.

    The final goal is make it simple as possible to be used with different material (like in the screen, the simplicity give me a possibility to apply that on a lot different materials).

    Thanks you and sorry for my horrible english !
