Shadow problem, day/night cycle

[Stangi]

Hey, I'm having a problem with shadows in my map when I have a day/night cycle. The shadows flickers very much, and it doesn't look good at all. I'm fairly new to UDK and don't really know much about how I should make the lightning when I have a cycle. I'm using a simple DominantDirectionalLightMoveable as the sun and rotate it slowly with Matinee. As far as I understand, having a day/night cycle means that all shadows are dynamic?

I've uploaded a video showing the shadow flickering, so take a look, please:

Now, I made the day/night cycle after a tutorial, but the shadows are not flickering there. Basically, I'm just asking how I should set up the lightning using a DominantDirectionalLight that rotates. Can anyone enlighten me?

I think there's some settings for the modulated shadows that you can mess with to improve quality

Where do I find settings for modulated shadows? Sorry, but I just can't seem to find it. I did find a LightShadow_Modulate in the dropdown menu Light Shadow Mode on the DominantDirectionalLight, but it won't allow me to set it to LightShadow_Modulate or LightShadow_ModulateBetter?

Still can't get it to work properly... Anyone?

Somebody knows what is that problem that I have in cycle day and night...it shows up that colors when the sun goes down.
Help me please.

do you use cascaded shadows?

Bump. Having the same problem as Stingi, no idea why. It's definitely caused by moving the light reallllllllllllllyyyy slowly.
