I have been struggling to create a frosted glass that is frosted on both sides. See attached images, I am able to create a generic material with colour white, and transparency to make frosted glass. However, it is only frosted on the side that the sun hits; once you enter the building it's just slightly dark and fully transparent.
I have tried using generic and glass on a curtain wall panel, and I have also tried a generic mass with generic and a glass material. I always have the same issue of the glass only working one way.
