When it comes to texture mapping, I'm all for the painters because I have painted several aircraft myself ... I'm not a fan of flip it upside down and mirror horizontally or vertically, I am a simple guy :-] or trial and error paint kits where you have to constantly repaint an area to get it to align correctly.
The POSKY 777 paintkit is a good example of how I would texture map...I would create a master paint kit with the entire fuselage all together, where you can easily paint the aircraft, then with added guides, all the painter has to do is cut and paste and align and they are done, what they see is what they get, NOT what they THINK they will get, I strive really hard to make sure of that!!
Simmer's Sky also has full fuselage paint kits, those are winners for me. I also hate paintkits with complicated grouping of parts, again, Im a simple guy, I follow the KISS method; Keep It Sime Stupid, lol.
