following shader script is useful to get chrome or reflection…

Shader “FX/Mirror Reflection” {
Properties {
_MainTex (“Base (RGB)”, 2D) = “white” {}
_ReflectionTex (“Reflection”, 2D) = “white” { TexGen ObjectLinear }
}

// two texture cards: full thing
Subshader {
Pass {
SetTexture[_MainTex] { combine texture }
SetTexture[_ReflectionTex] { matrix [_ProjMatrix] combine texture * previous }
}
}

// fallback: just main texture
Subshader {
Pass {
SetTexture [_MainTex] { combine texture }
}
}

}

I know this is the old post, but it appears in google search of “unity chrome shader” - so here we are, my chrome shader. It does not uses real reflection, as author asked, because it’s a quite expensive and requires Reflection Probe usage. Instead, it generates “pseudo-reflections”, based on view angle.
