Alpha Layer Materials

I am currently modeling a chain length fence and imported it to UE4. For the chain I have used a separate material than I used for the pipes so that I can use an alpha layer material and see through between the chain… Well I cannot get it to work. I saved the chain picture with the proper alpha channel and imported the texture to the editor. I then made a material with it and applied it the the model but all the alpha channel shows up white. Is there a parameter in the blueprints that I need to change to enable this or am I going about this in the completely wrong way? I attached the material blueprint.
Thanks

Set the blend mode to masked and connect the alpha channel (white link from the texture sample) with the opacity mask

Works great, Thanks!
