This looks quite interesting but I realize that this might result in a
bigger task because rain looks very different depending on where your
viewpoint is (inside/outside) and at which speed you are cruising.
Your model matches the "rain while sitting on the runway, waiting for
clearance" situation. Rain during flight in a small four-seater looks
like the screen steaming up combined with heavy clouds which a changing
weighting depending on your cruise speed.

I can't tell how rain looks at 150 kts and more

Heavy precip in a PA28 at 80-110kts looks rather like an upwards waterfall on 
the windscreen.

Well, this will only cover a part of the rain problem. But I noticed 
there is a huge difference in appearance with different frame rates. It 
looks as expected on my O2 but it's totally screwed on my PC. :-(

I had an idea a while back that being able to change the specular material 
setting for runways / taxiways 'on the fly' could produce the sort of wet 
'sheen' you get on asphalt when it rains.

Good thinking!
In the mean time I've updated the rain animation again and fixed several 
 issues.
