Automotive glass alpha problem

Hi, I’ve been testing some rendering with the automotive glass material in ray-tracing and I keep getting this weird effect. Image attached…basically when looking through another window the backface of the glass behind renders as a grey cloudy see-through material. Any ideas anyone? Thanks

Is it set to two-sided lighting AND shadowing in the object (the window on the other side that’s grey)? Also, does it and the lights have Transmission enabled?

Ok thanks, I tried these but still the same :frowning:

RT translucency seems to be currently broken in ue4, i have tried everything but nothing worked.

Ah ok, are you using 4.25.3 ? I’m still currently on the previous version so maybe update could work?
