Probably a super simple fix, but what is this grey box and how do I get rid of it? It seems to be tied to the Model as hiding the Model also hides the box. I spent hours combing forums for answers and the closest I got was Texture Space, but that didn’t end up being the cause.
if you look closely in the grey area there are diagonal lines that might give a clue to were its coming from? Also a full screenshot of your setup in the outliner will be helpful.
