This is an edited cockpit livery, but also a mod.
Cockpits can have liveries just like the external model of an aircraft. However it's not as popular, and for most modules comes with only a few versions, such as "Native", "English", "Russian" or "Chinese”
I cannot create a separate livery for the cockpit, as for whatever reason DCS will not see or acknowledge it. It only will if the modded cockpit livery is named "default." Thus, this mod cannot be added along side the default cockpit livery, it must be overwritten. I'd suggest taking the "default" cockpit and backing it up or something first.
The most important change this mod does is remove the smudges on the inside of the canopy glass
