Get the graphics from this link
http://www.weedicom.co.uk/temp/skies.zip
with your world cube thing selected, press 'Page Down' and select 'Sky' check box
Press 'Page down' again
Go to 'Template' mode ( hit the tempate tab)
Press the 'Sky Box' button on the right hand side, a dialogue will open
the graphics are labeled 1 - 5
Put #4 in the Left box
put #3 in the Back box
put #2 in the right box
put #1 in the front box
and put #5 on top
and there you go - should work - nice blue sky with a ridge of high pressure.
Of course there are problems as the skybox is obviously no longer supported.
Look at the Skydome entity as mentioned earlier in this link -its interesting
Still haven't got the script thing to work properly, you can use a texture there but I haven't made it work - will do when I have some energy
enjoy - Larryboy
