So I have Skymaxx 5 installed with FSGW and RWC all working fine. METAR calls for rain and it's raining in the sim, but NOT on the windshield in the COWAN SIM Bell 222B. He doesnt use librain as far as I can tell.. When I manually turn on precipitation in the Xplane weather sliders I get rain on the windshield... Any idea how to fix? Thanks, Rick
