I was trying to view the original .fbx files for some of the assets in the content examples. When I click view in finder they only show up as .uasset files. Is it possible to view the original fbx, or do I have to export/migrate these files?
You will have to export them manually. You get only .uasset files once you import assets into the engine. If it is your own asset created and imported in the same computer you can tell it to find the source file(Show in Explorer), which isn’t the case with downloaded assets.
