ShaderLab - 3DText.shader

Shader "GUI/3D Text Shader" {
Properties {
_MainTex ("Font Texture", 2D) = "white" {}
_Color ("Text Color", Color) = (1,1,1,1)
}

ShaderLab - 3DTextOneSided.shader

Replacing "Cull Off" to "Cull Back", makes the text one sided.

Shader "GUI/3D Text Shader - Cull Back" {
Properties {
_MainTex ("Font Texture", 2D) = "white" {}
_Color ("Text Color", Color) = (1,1,1,1)
}

SubShader {
Tags { "Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" }
Lighting Off Cull Back ZWrite Off Fog { Mode Off }
Blend SrcAlpha OneMinusSrcAlpha
Pass {
Color [_Color]
SetTexture [_MainTex] {
combine primary, texture * primary
}
}
}
}
