UI Material and texture alpha

Hi, I am working on an UI for a fps game.
I want to apply some effect on fonts and images but have a problem with the texture alpha

This is the texture I use:


and this is how I want to see it, (but without the black background)


Can I avoid that black background? I cant figure out where must I use the texture alpha in the material



Put your alpha in the opacity slot.

Mootjuh, thanks for your reply!
I’m sorry, I don’t realize where do that…
Because I’am using the opacity slot of the final node for the general transparency

Thanks again!

Mootjuh, You were right. Thanks for your help!
