Answered: Glass transparency

Hi , I am studying in 3D modeling and i'm currently doing my final project. I tried incorporating Quixel and Unreal 4 in my workflow and i stumbled on some problems with glass and its transparency. I want to texture a lantern i modeled in 3ds Max which has 3 little windows/glass and a candle inside. Problem is that i cant figure out how to make the glasses actually transparent so we are able to see the candle inside the lantern. I tried using the glass smart materials and adding an opacity map in quixel but its not working. Could someone enlighten me on the process of creating such a material which will be visible and has the desire effect in Unreal Engine 4. Here is the lantern. 

Thank you
