I am having problem with transparency. I used traditional method for transparency ( black color in opacity).
http://prntscr.com/byhwsa it is for practice only. Right now i am working on the front plane,the green area i want it to be transparent

http://prntscr.com/byhxnj green material opacity layer which is black so technically it should be transparent.
Why it is not showing transparent and what am i doing wrong?
