I just made an SVG paintkit from the XCF paintkit for the 707. I get confused about the versions of the 707 that are out there -- I'm using the one from latest Git.
https://dl.dropboxusercontent.com/u/283 ... intkit.svgIt's got a "common" paint layer, then layers for PAX and cargo so you can make cargo and PAX liveries for the same airline in one file. For exporting the PAX, hide the layout, cargo paint and cargo fittings. For the cargo, hide the layout, PAX paint and PAX fittings. Obviously you'd need to export separate .png for cargo and PAX and create two .xml files. Some cargo planes have the windows in, in which case, don't hide the PAX fittings (which is basically the windows).
Export at 2048x2048 rather than the 1024x1024 used on the existing liveries.
I haven't done anything with it yet other than a quick test, but planning a British Caledonian and British Airways (rather than BOAC) for the 707.
