Hi,
If you could model the visual effect of rain (and possibly oil and/or fuel, coolant, and blood?) upon the cockpit glass this would be something of a shock when encountered.
I'm currently doing some research on the FW190, not in BOB I know! But he British noted that although it's canopy provided great all round visibility, it's visibility was poor in the rain. This was further complicated by the fact that the 190's canopy could not be opened in flight.
In BOB, Spitfires and Hurricanes would have some visibility when landing in the rain because they could open their cockpit, the 109 had sliding side windows, which would give some visibility to the pilot but would make landings even more difficult than usual.
Flying inside the glass dome of He111 in heavy rain would also be be pretty impressive visually. If the sound of the raindrops crashing into the planes glass could be added it would be even more amazing and immersive. What German gunners would see from a glass canopy in the rain,would be minimal, I'd have thought.
There must have been occasions when fighting over the Channel in the rain, it would have been very disorientating for attackers as well as defenders. I'm no programmer so do not know if this would be difficult to implement. There were a few missions fought in thunderstorms in IL2 but visibility was always good enough to allow game play. With BOB being the next generation simulator, having to return on instruments to base because of the weather visibility would be novel, don't you think. The weather over the channel can change very quickly from sunshine to rain and back, especially in summer! I know, I live here!
Also 109 wing slats that bang loudly when they open in combat would also add to the tension/terror when dogfighting!
Best Wishes
