In my humble opinion the guys that designed the game really over looked the skinners. They have also have not been consistent and have not allowed overall flexibility even via there text files as to the position of unit codes, they also don't include all of the units text files only some. They have ruined the Spitfire template which now looks ridiculous. As long as they have control of the void template which can't be corrected I feel your far better getting the overall paint scheme right and not worry about the rivets etc because they override all this plus their weathering tool also can override the skin look. If you leave the rivets out when they change their template your skin wont be affected. If your rivets are slightly out of alinement it will affect the skin's look. Also when you look at photo's you can hardly see the rivets anyway. Don't get caught up in the small stuff.
Their like an elephant they wont budge. They could do so much more but Obviously wont which is a shame for historical buffs like me who like all the historical correct markings.
