Unity imports fbx and moves the midpoint. HELP

I have Imported my turret to unity but the midpoint has been moved, How do I fix it? I have exported it as an fbx.

You probably have the “Tool Handle” button set to “Center” rather than “Pivot”. It looks like this:

And to use the model’s own pivot, it should be this:

It’s also worth familiarising yourself with the effect of its neighbour toggle button which switches between global/local coords.
