OK, so after some experimentation i have worked out the following:
After you start Unreal Engine you’re greeted with “Select or Create New Project” screen.
If you start a project with “Film, Television, and Live Events”, then there are no lens flares and the sun remains a sharp round shape. If you create a camera, it also won’t create lens flares (even if you turn them on), although it *will *create some other FX like grain jitter.
If you start a project with “Architecture, Engineering, and Construction”, then you will have lens flares by default and your sun will also have a more diffuse look. The lens flares can be turned off when viewing the level through a camera.
But that still leaves me wondering: where in UE are these lens flares and sharp / diffuse sun settings? I can’t see these settings anywhere. Neither Google nor UE docs turns up any info about it!
Or are these simply different “engines” and i just need to accept this as a fact and move on?
Thanks, hopefully, in advance!
