This is a small detail so if it doesn’t get fixed, it’s alright. In case you don’t know what I’m taking about, here are some photos to show:
BA B777-300ER in real life:
BA B777-300ER in IF:
If you look closely you’ll notice that the color of the back of the engine is different in the two photos. In real life it’s a nice silver color but in IF it looks like it’s extremely old. Some B777 do have the same thing as IF but they’re mostly B777-200/200ERs. The 300ERs and B777F’s all have the silver color which looks much nicer. Also just to clarify, the 200ERs don’t need to be changed because that’s what they look like in real life. Like I’ve said before, this is a minor detail so it is by no means a priority. It just bothers me when I see the brownish color on the engine. This is just another detail that will make the 300ER/Freighter aircrafts even more realistic when the rework is finished.
