Experienced modders able to fix that "glass issue" in a few moments by multiple solutions what can be shader, material or texture correction. ;)
Honestly, ED could be 1 or 2 years ahead, if they have entrusted some modders and developers to fix issues and upgrade various things.
These images more than a year old and came from a hidden facebook page: U.M.A.D. (United Modders, Artists, Developers people have 10+ years experiences in DCS-LOMAC, PS, MAX, programming languages etc.)
They fix issues immediately when bugs appear (Mi-8, UH-1, MiG-29, UAZ, GAZ, structures etc. glass issue too) while we were waiting 6 months for the official Mi-8, glass issue fix.
Shame but the official UH-1H windshield glass parts are still not a glass material today. :doh:
