From the moment onward I first saw a rain tutorial for Half-Life I've wanted to create a map, which would utilize this effect. The very first rain tutorial I read used an env_beam entity to create the rain. The method was slow to implement and very hard on the entity budget. Later on I came across a different kind of rain tutorial which used func_conveyors instead of env_beams. Three years have passed since I first read that tutorial and now I've finally begun to make that Half-Life map with rain in it... Due to the fact that I'm currently serving in finnish army it might take a while for me to finish this map, but all in all I'm determined to get it done.

I've also done some experimental metal textures. All feedback from negative to positive is welcome. I've update(and upload more) pictures on my next leave from army, which should be next weekend.
