I am so desperate right now.
My 3 months' worth of work just completely gone in a few seconds after I hit "Build" for my level.
So I messed around inside the "render" tab inside "Project settings" in hope of achieving a better-looking result for my scene. I remember enabled "Forward Shading" and after hitting "Build" my whole scene looked completely washed-out and flat (All my materials just don't look right at all, although transparent materials look very good). So I went back into Project Settings to disable "Forward Shading".
Later, no matter how many times I restart and rebuild my level, I just couldn't get back my level to how it looks like before.
I greatly appreciate any bits of help or suggestions.
