Custom Worldspace - Setting Region for Music, Lighting and Climate

[Hellscreamy]

We are currently working on a large worldspace mod which has many zones in it with different climates and atmospheres. I'm trying to set the music, lighting (different mist colors and such) and climate for a region. However, I can't find any tutorials on setting lighting and climates for worldspaces, just for interiors. How can I add these?

I found a Region Editor where the Tamriel worldspace has different colored cells in which the sounds are determined, I don't know how to do this myself though.

 

And on another note: Where or how can I find the meshes and textures for the sky and sun so I can change them in my weather/climate.

 

Any help would be appreciated.

 

EDIT: I really need to learn how to use the search engine here, found this topic in the mod talk section which explains how to work with regions. "Can you make the climate and music of a worldspace change at a certain point?"
