Scene renders perfectly in 3D view with rendered drop down list but black when render

My scene looks correct and well lit using lamp and hdri in 3d view and with the rendered drop down list selected.
10 million polygons.

But when I click render, all I see it black. Pure black.
Please advise, thanks.

I solved the issue, the bounding box I used to guide the camera animation was not set to “not render” and is blocking the view. Silly mistake.
