Hello, I am having a weird bug in Unreal Engine; When I create a project, close it, and then reopen it, sometimes all of the meshes somehow become… transparent? Like for example I have a blueprint of a gun, and it becomes completely invisible in the level. If I open the blueprint viewport, It is semi-transparent. This happens across all the levels in that project, and once it happens, there is no amount of restarting that can fix it; the project is basically doomed. Has anyone experienced this before? Or at least has any resources that could offer a solution? Thanks
