All of my actors in every level appear semitransparent, with some objects entirely invisible, a few nearly opaque, and others just barely visible. The seemingly visible objects are evidently problematic, with shadows passing through them from the other room. These shadows are also very buggy–changing shape, disappearing, and reappearing at times. When I test the game, nothing changes and I can even see through the mannequin to its joints. I have no clue as to what is causing this issue and it simply occurred one day when I opened the editor. I have attempted to solve the issue by recompiling shaders as well as rebuilding lighting and refreshing the project by deleting the non-essential folders and rebuilding the code. Additionally, I found that other projects on this computer work perfectly fine, which further baffles me.
