Editing an Existing Skybox

[IrocJeff]

My knowledge is limited here which is why I am asking. I have two routes I want my level to go weather/terrain. One is using snow and one can be in a thunderstorm. The issue at hand is that my terrain works, but, the stock sky boxes don't fit with what I want to do for Jedi Outcast. There is a sky called ICE but that just makes leak and doesn't work. 

 

Is there a way to modify an existing sky shader that I know works and make a new one to look like a snowstorm or thunderstorm?

Nevermind. Close this up. I found a tutorial on it a few hours after I posted. Sorry!

@@IrocJeff I will close it, but do you mind posting the tutorial you found?

Its the one from Rich Diesal's tutorial. Granted, you'd have to supply your own images, but, you'll more than likely borrow existing values from the stock boxes for light and stuff to get the hang of it.

I found some free skybox images here after I posted. The images may have to be altered with photoshopor the gimp for size and filetype.
