Newby needs a little help

Before I get too deep into learning another major software package (Maya, PS, Terragen) I would like someone to tell me if this is readily possible in UE4. I want to use its scene creation capabilities to help in producing a large poster size image.

Can I create the scene in UE4 and render a camera shot out at, let’s say, 6000x4000 (300dpi) for further post in Photoshop?

There you go. That, or if your pc is an absolute monster, High resolution screenshot at a high multiplier.
