Day/Night System - [Request]

[pesdelisi]

I have a simple day-night system map [DOWNLOAD (http://dl.dropbox.com/u/6827713/Day%26Night.udk)].I want to learn how to rotating light and how we will make sky ? *cloud etc. -not like cylindrical system

I worried to make a good night/day cycles system too, but once I found simple decision:

First off all, the highest sky is in night without any clouds. I decided to make a FULL-sized sphere but with - (minus) size (I mean that this is like a simple sky with textures on the inside). One half of this sphere is using "Skydome" texture, and another is using "sky" texture. And I'm forcing this skydome to rotate .
The second sphere with minus size too will be smaller - It will be the sphere with the only clouds (other pieces is using only Alpha Channel). It's a full sized sphere too. I'm forcing to rotate this sky. And with only kismet we are making a skylight, that are changing the self parameters.
And a very important thing - the map is need to be saved to one file, the sky with the skydome to another file, and the clouds with the light and visual post-process volume in the third.
Then at the game we are combining these files at one, and when we need to make a very cloudy weather or overcast weather, we just replace the clouds in the game to dummy with a light or to a many clouds with post-process and a rain.
This system is giving us possibility to make day-night cycles and even dynamic weather ! One problem is to smoothy combine all the sky with clouds, lights and post process with another. But it will be very cool, I think

Im already know how to add sky with skydome etc. but I was said without skydome or sphere/cylindrical system.

And if we give a sample in UDK: THIS VIDEO (http://www.moddb.com/groups/udk-developers-group/videos/daynight-cycle#imagebox)

that was very cool! will you be showing how to add stars to the night cycle on the next possible segment?

I hope so cus that would be so cool!
