Thanks all.Yes it works. But I seem to remember the original FSX rain effect was influenced by airspeed.So that it moved up the screen when speed increased and almost disappeared when the speed was that much faster.As it is, it seems a little odd to be motoring along at 140 knts and the drops are runnning down (forward in effect)!But I am not ungrateful it cures the problem which prevented any flying.Nigel

Ah, that's a result of the modeler not properly orienting the UVW Map for the windows such that the "raindrops" would "flow" in the proper direction. Unfortunately, there's nothing the end user can do to change this... :(

Ah so maybe I should have tried other aircraft than just he Mooney.I will look at others and see.ThanksNigel

this reminds me of taking off in a rain storm in fs9, in the dreamfleet 727, with Cloud 9s LAX... what an atmosphere. the sounds of the rain and the windshield wipers was great. I really miss that bird :( So if we download those files it won't break anything on other addons, just give us rain effects finally for some of the planes?

Maybe there's an airplane above you with a leak in the toilet water pipelines :(
