Rain effect on windows[SOLVED]

[Vradcly]

Ok ill have to ask for some help again...I know I found a custom story once that used rain running down the glass of some castle windows and it looked really good, but I cant find it...

I am currently trying to do the same thing.

Tried making my own particle effect, but whenever i give the water particle a fixed axis to run down from it stops working, so i can only use particle water effect if i can live with that the axis is not fixed but follows the camera (like lightrays, unless you fix them). And that is not acceptable, since it will make it look like the water is running down anything from the wrong angle....

I tried making a plane instead, and used the streaming sewer water and after much editing got it to look somewhat ok (only a bit too green...), but primitives are not possible to activate/deactivate, so that plan faled (its not suppose to rain all the time).

I tried making a water area right at the window glass with waves that could produce the wished for effect, but no that did not work at all. Then you need to have something at the window always make waves....

Well now im running out of ideas, seems noone have had this problem before, google and forum search gives me nothing, I want to find that custom story that had that so I can look at closer at that. Anyone have an idea on how to make rainwater flow down a window?
