I lke the graphic, but it causes some errors. Like doing a news submission took me 25 minutes today. It kept telling me I am not authorized to do the action. But try try again and I got it to work.
I think it's the script itself that produces pc-lag. I have put down the max size and the no. of snow. Hope it's better now. If not, please tell and I disable the snow or try to put only in startsite.
Take a piece of script, some units, a map and some triggers, put it in the editor, mix it and you get a great cooked mission
