Please answer two-sided textture

I know this question has been asked multiple times. However I still can't find an answer to it. How can I make it to two-sided texture. Is there an easy way to do this.

The question has been answered dozens of times on the Unity forums, where it's very easy to find the answer with a search. It's also been answered here, which you could also have found right away with a search on "two-sided" or "double-sided".

I did search for the question. 12 of the answers that I found that did not work this is why it's probably asked so often.because does alot them actually do not work.
