Hi Eric,

Yes. We've implemented rain, but have just been told by our "client"
that it's unsatisfactory. :-(

We used billboards, and made a texture in Prisms that is basically
a whole lot of alpha blended vertical streaks. When you have a number
of billboards in front of each other, and they're rotating, you sort
of get this animation effect that I thought looked ok.

I have been told that rain is not a column, and that it should get
denser as you approach it, not larger. They'd like to see fine droplets
of water! So, we're open to a new idea as well...

ben.
