I’ve got a question in regards to UE’s refractive material options and window glass. I’ve got a window glass pane that is around 3mm thick (so esssentially a very thin cube) and sits inside a frame. The struts of the frame are considerably wider than the glass, so they protrude on both sides of the glass pane.
My problem is that at extreme viewing angles (looking at the window frome an extreme side angle), there suddenly seems to be a second frame behind the window. You can see this in the screengrab comparision below. This is obviously a quirk with the refraction functionality inside UE.
I’ve watched a lot of tutorials and read through this forum, but none of the solutions seem to fix my issue. Attaching a color node to the normal input of the glass material does help in cancelling this effect, but then all refraction is gone, which is not what I’m after.
Maybe there’s someone who could help me with this? That’d be great
