I work in Archviz and we use ue4 for VR and animation. We can Not use it now for images because there is no perspective control. Without it it is impossible for a good render image. This is Because architectural renders need to fix the wide perspective. I think UE4 will be used way more when we have it. Also the images will be more beautiful.
You can control the amount of perspective with field of view. If you want no perspective you can use an orthographic camera.
Hey ClockworkOcean,
Thank you for your answer but unfortunaltiy this is not what i meant. Perspective control gives you the abiltiy to correct te perspective:
Perspective control is a procedure for composing or editing photographs to better conform with the commonly accepted distortions in constructed perspective.
