Alright Sakai,
I made some tests and I have to say that changing the design of the engine cooling vents in the"Alpha_Channel" layer
will not do any good.
The skin will show a cut-out area - but it will also let the viewer see the other side of the aircraft or even the sky.
See this screen...

So this option is not good.
The best way to show whatever new design you paint on your skins, is to simply remove the "alpha-channel" areas which
are painted in black. By painting these areas in White-color the aircraft will have a solid area. - Do not paint the entire alpha-channel
in white color, just this area around the engine air cooling vents.
I have made a test by painting in the default skin with my version of the engine cooling vents. I have also added the Japanese roundels from
eMelĀ“s skin-template.

So, if you want the default skins to have this area to look solid, you will need to paint ALL the default skins "alpha-channels" and
and then save each skin in 1024x1024 size "skin1o.tgb", 512x512 "skin1o.tga", 128x128 "skin1p.tga"and 32x32 "skin1q.tga".
AND
also re-paint ALL the default 50+ skins to have this new detail on their engine sides , because those default skins do not have this painted on them.
Then it is possible to have the same look as in the WW2 photo

This is my version of the skin details - Size 1024x1024 (PNG format)
use it if you wish on the default skins. Just place it over any skins.
