"50 Shades of Grey" ... well ... almost!! In the repaints I've collected, it appears that there are three different shades of grey used - and these also differ depending on whether they have "burned in" shadowing. I think the "hard" shadows were added because of deficiencies in light mapping in the old models. "Cheese Strike"'s livery doesn't have them, which could account for why they look a little "flat".
As to the "alpha/no alpha" issue, there's absolutely no difference - other than slight transparency changes to some of the cockpit windows (with alpha-included being better). Hardly worth agonising over, but I'm intrigued as to why LM would include "no-alpha" textures in an official update.
Anyway - here's a list of the 8 liveries I have (and who did them):








The two Alex James liveries are the darkest, the Cheese-Strike one the lightest, and Dave Sweetman's somewhere in-between.
Please don't ask me for links (!!). Some of these liveries have long since disappeared from their original hosting locations - and have been sat in my backups HD. I've tweaked many of them (adjusted props, flags etc.) so I'm not sure whether I'm allowed to rehost them somewhere. If I have time, I could try and contact the three authors and see if they will allow me to compile one complete packege of all these and host them.
Here's Dave Sweetman's 2016 NZ7003 mapped onto the EICAS model (just to test the glass cockpit):


The glass cockpit panel works fine, BTW.
