Problem Solved, See my Reply Below.
I was checking out a 3d model on FAB and opened the 3d viewer. A new option popped up on the screen asking me if I wanted the regular orbit navigation, or unreal engine navigation.
I clicked on the unreal engine navigation because I wanted to see what it was like, but I instantly found it really hard to use. I much preferred the old orbit navigation like Sketchfab has.
The problem is that I can’t find any setting to change it back to the old orbit navigation type. Does anyone know how to change it back?
