These are better templates, even if they also aren't multi-layered (they are also official).

Try some of the user made templates at the site too. They are multi-layered.

Rivets and panel lines you can't change.

Some skins have default warnings and stencils (ex. Hurricane, Bf 109) though it varies a lot between aircraft, and some have very little. I added lots of stencils and warning markings to my Heinkel 111s at that site. You can can usually find some extra things to add to an aircrat if you want.

I'm not sure what you mean about markings. You can turn them off in-game for your aircraft, (or for any other aircraft using Full Mission Buider and un-ticking the appropriate box). So any sking you make can have it's own roundel if you have added it during the making of your skin.
You can't make custom roundels of your own and have them automatically applied to aircraft.

[Edit: The templates I linked to above seem to be a combination of the default weathered layer, and rivet/panel line layer. They originally came from the Cliffs of Dover french forum, but they have definately been made by someone with access to these two layers]

Thanks for your reply mate.

Yes I have those .fr skin templates also - about them, they seem to have a lot of detail that the original ones do not have - what gives? Will those show or be overwritten?

If you are making a skin by using multiple layers then you can use both of the different templates as a guide to help with skinning.

The rivets/wear layer will show where the rivets and panel lines are, so you can copy/trace them if you like...or you can even lighten these lines if you want to make them show less (by selecting them and making them lighter, or invertineg them). Or just reduce the opacity of the layer to show just a little wear.

Use the other layer that you posted (in your first post) as a coloured guide for where the edges of the different parts are, and where the camouflage patterns should be drawn.

You can create quite interesting skins despite the limitations of default panels/rivets. Finding where all the different parts are on the texture is a bit time consuming, but once you have done the first skin of an aircraft type the others become a lot easier.

Tip - I make my roundels and markings separately to the skins, then it's easy to just add them to any other skins you make. Make them large and they will look better when shrunk to the right size.
