Render overscan in UE4 ?

Hi guys,

I am tryting to render out the CG images in UE4 and comp them in Nuke but I got stuck how to render overscan in ue4 like in Maya. I can’t find anywhere talking about rendering overscan image in UE4. In Maya multiply render resolution 1.1 or 1.3 in render setting and then change camera scale in camera setting in Maya.

But I have no iead about what ‘camera scale’ is in UE4.

I hope you guys know the answer.
