For some reason, the model I am currently working on does not appear to show any lighting or reflection. The strange thing is it appears just fine in the editor, but it is when I save and exit that it now appears flat and lifeless. It was working just fine for several weeks, but just recently started exhibiting this issue. I had temporarily resolved the issue by switching from PBR to the classic renderer and back, but now it is back in the problem state.
I was scheduled to release this model to my Patrons today, so I was hoping that I might be able to resolve this issue soon. Thanks!
