Couple more mod related question:
Are the aircraft skins under "OBD Aircraft Skins" already included in the WOFF UE skin pack?
Is the "WOFF UE - (300) Blue Triangle and FPS Improvement (Version 1.0)" -mod still useful or has the game been updated with similar fixes since the mod's release?
No, I think that the skins on the mods page are not included in the UE skins pack.
Not sure if that particular blue triangle mod is still useful but my understanding is that one of the blue triangle mods is now built into the very best mod of all - the Mission Editor. If you're interested in the Mission Editor you should download it from this forum instead of the mods page (you'll get the latest version - 1.8.5). See here -
