I increased the shaders levels and now instead of seeing the rain, I see it hit the windshield, which is super cool. I have some questions.
One, how do I get the rain back so I can see it falling?
Two, since most of my flightgear usage will be without an aircraft model, how could I still get the windshield effect without a wind shield. In other words, what is the rendering basing the rain effect on? Is there a "windshield" model which cause the effect to render or some other magic?
Could I/Should I make a simple model which has just a windshield?
