UNITY Prevent 3D Text Render Trough All Object Without Shader

Question

im tired of those answer i found trough search engine that just keep saying " the trick is to modify the shader " without thinking because they want to gain reputation , in my case , i have 2 3D text , one of them using special font and the other one using default font , and the shader to prevent the text render trough all object from http://wiki.unity3d.com/index.php?title=3DText is not working and giving weird white square plus i don't want to change from default Arial font because i want to make them look different , i also cannot use sprite as background because i need to change their color trough script to give some effect , this is my picture showing my problem -- :

After adding material :

Proof i still can change the color of the object that have the material in it :
