Hi, I really miss a proper rain effect on windshield in X-Plane. There's something if you have a 2D cockpit, but most of the new planes comes with 3D cockpit and none of them so far has kind-of-a-real rain effect. It's tricky and/or resource heavy to calculate the raindrops. But since we can hack around OpenGL directly as a texture we might have a solution. This is done in WebGL: http://tympanus.net/Development/RainEffect/ Sadly I don't have time at the moment to pick this up and kick start the development but if somebody is interested, could be a good starting point If nobody picks up in the upcoming months, I might have time to do this when finished with the v1.0 of the Let L-410.
