ISSUE DESCRIPTION
Windshield rain disappears above ~4,500 ft AGL across multiple aircraft (Fenix A320, Default A320, CSS 737-500).
Below ~4,500 ft, droplets render normally on the windshield. Issue reproduces with the built-in Storm preset and with Custom weather (overcast layer from surface to ~23–24k ft, Precipitation = max, Humidity = 1, Temperature MSL 100–120 °F to keep liquid precip aloft).
This looks like an altitude-dependent suppression of the windshield precipitation shader (not a temperature or live-weather issue).
Build: 1.39.9.0
DirectX: DX11
Cockpit view: rain stops ~4,500 ft AGL, returns when descending below that altitude
Weather:
Preset: “Storm” (also Custom)
Custom details used for repro:
Cloud Layer: Coverage ≈ overcast, Bottom −500 ft, Top 23–24k ft, Density 1.0
Settings: Precipitation MAX, Humidity 1, Temperature MSL 100–120 °F, Snow depth 0
Live Weather: OFF for all tests
FREQUENCY OF ISSUE
Every time (100% repro) following the steps below.
REPRODUCTION STEPS
Launch a flight with Live Weather OFF.
Select Storm preset (or set Custom as described above).
Spawn C172 G1000 (also repros on A320neo, Fenix A320, CSS 737-500) on runway.
Confirm rain on windshield on the ground.
Climb through 6–12k ft while remaining within the precip layer.
Observe: In cockpit view, windshield rain disappears above ~4,500 ft AGL. Switching to external camera at the same altitude doesn’t seem to show rain as well, can’t tell as it’s very cloudy.
Descend below ~4,500 ft AGL → droplets reappear on the windshield.
