    Parallel light/shadow lines ?

    Hey all,

    I'm having a really frustrating problem, as illustrated by the attached screenshot, where annoying parallel shadow/light lines form when a directional light is nearly horizontal with the surface (sunrise/sunset style). I've tried using a moveable dominant directional light and scoured the net for answers with no luck.

    Any UDK afficionados among us care to enlighten me ? No pun intended :P. Would really be super helpful, and much appreciated.

    That's shadow acne, an artifact specifically related to dynamic lighting.
    If you don't need whole scene dynamic shadows/lighting, just do a rebuild of your map.

      Well I was hoping to implement a day/night cycle, is it possible to do that without dynamic lighting?

        It's really obvious when you have a flat plane like that, a lot more detail and surface deformation helps to break it up and disguise it.
