not sure what you expect it to look like. translucent support refraction and is properly reflecting. it will not show up in mirrors tho.
if you want that you gotta use masked with a semi control via the dithering effect. it’s temporarily unstable ofc.
i gotta add… some options required for this type of sceneario are not properly applying in the postprocessing editor nor when switching into game mode. they work however when you enable them via commandline on begin play or map load. that’s for proper ingame control to only use them where you need them.
