Fixing the 3d text always on top layer problem,

左邊係我地常出現的情況，右手邊係我地想要既情況

以下方法不能使用預設FONT,要import 字型入去，我用勘亭流做例子

將字型IMPORT入去ASSET內，在inspector的character 轉成unicode,再Create editable copy

甘生了一個字型texture出來

之後在ASSET Folder Create 新既shader

Shader "GUI/3D Text Shader" {
	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 Off ZWrite Off Fog{ Mode Off }
		Blend SrcAlpha OneMinusSrcAlpha
		Pass{
		Color[_Color]
		SetTexture[_MainTex]{
		combine primary, texture * primary
	}
	}
	}
}

之後在ASSET Folder Create 新既Material

New Material 內Shader部份用GUI->3D Text shader 即係剛剛加入的Shader

然後Texture 加入剛剛做出來的Font Texture

然後去3D Text Object , Mesg Renderer內materials 由Font Texture 改為new material，甘就可以了
