The Bf109 in my template had the rivets added one by one by myself using the default 109 skin that was included in the first download pack given to us by 1C/IL2 team (don't know what to call them exactly). Luckily that 109 skin had rivets and panel lines done on it, unlike alot of the other skins.
As for the Bf110, I'm trying to transfer the lines and rivets from the void skin, from good old IL2:1946. Not going to be as easy.
ps.. your welcome
And for the record.. I'm not asking the 1C/IL2 team to provide a multi-layered template or anything crazy... Just a void, one layer skin would do (even if we can't change the "hardware" or the "panel-line overlay" I mentioned above in game.
