Rounded corners for Photorealistic result

Hi,

I would like to make archViz with UE4. I’m starting to learn UE4 and I need an advice.

Usually, In my renders, I make Rounded Corner of the Architectural elements for getting a best photorealistic result.

3DS Rounded corners Doc.

My question is: Is this step necessary in UE4 model for archViz purpose?

Thanks

This not implemented in unreal render. And I never saw it in realtime engines.

So if you need this for your visualization, you should make it with meshes geometry or normal maps.
