3D Text Shows No Matter What's In Front Of It... (552691)

Does anyone have experience in Making 3D Text Not visible through walls? Nobody on Answers seems to help, They linked me to this website:

http://wiki.unity3d.com/index.php?title=3DText

And I followed those instructions to the letter, but my 3DText can still be seen through objects!

I even did it step by step using this foreign tutorial video on the subject:

And that didn’t work either…
Is there just no way to make 3D text act like a visual element, like it should be anyway?

The 3DText shader on the wiki works as described and is the correct answer. If you’re still seeing it through objects, that means you missed something.
