Objects missing after packaging as Windows x64.

I’m just going to keep it short. I import my object as a FBX file, during importing, I do not see even a single error. I click Build icon, not just build lightning, then I save the project and assets. Then I package my project to be as a playable game on Windows x64 bits and my imported object just isn’t there, or anywhere.

Please ask additional questions if you need to know anything else.
