I’m a newbie at UE for ArchViz, but have to say the program is already delivering very good results for me. Of course I’ve a few problems, most of them trivial or with workarounds, but I’m facing one that I cannot solve nor explain. I’ve created a glass material which works fine, except for some strange artifacts at the edge of the viewport. These are bright colored spots/sparkles which appear when moving the camera around (see attached screenshot). The real problem is they show too in game mode and when I create a movie. I’ve searched a lot on the forums but cannot see anything similar nor a solution… please, help!
