Yeah I've actualy considered building it for Q3. Extra Millennium Edition Plus. Yer it just doesnt work in Q3 cause you have to do many shader pass' to get any density in the rain. All atmospheric and stuff. Yeah they could have implemented it a different way.
Many mappers find making maps more enjoyable than playing the game itself.
I realise that if I don't play enough I won't understand gameflow enough to execute it well in my maps. How do you begin a map. What are the stages you go through. A beautifully detailed map. Free for all.
