Weird parallel light lines in maps



  • 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.

  • It’s quite common issue when a flat surface is being lit at a very sharp angle. If you’re not planning on making directional light dynamic (like moving sun) you can build lighting and it should go away.



  • That’s just the thing - I’m planning on implementing a day/night cycle :P.



  • @Nightrise:

    Have you considered how this would function with those who turn dynamic lighting off?



  • I hadn’t considered that - I didn’t think many people did that sort of thing. Does somebody know if its possible to pre-bake a full day/night cycle for all static objects?
