I've made 2 tools for you guys to use when making skins for 0.4b+
In order for skins to show in Aurora they need to have 2 files:
a preview image named preview.dds, this needs to be a 256x144 Headered DXT5 image, for that i present to you: DDSConverter.rar
a data/meta file named skin.meta containing details about your skin; who made it? what's it's name? what version is it for? etc. etc. for that i present to you: SkinMetaGenerator.rar
Any questions? feel free to ask me! any bugs? report them to me so i can fix them!
Now, you're probably wondering, how do i use these tools? let's start with the DDSConverter: it's as simple as a drag 'n' drop, you drag 'n' drop any support image (bmp, png, jpg, gif, tiff) optionally you can specify the output filename as the second argument, normally it just takes the name of the input and replace the extension to dds
The second tool is slightly more complicated, it's a GUI tool which you run that generates the skin.meta file you need to have included, most fields are quite self explanatory, like author... that's your name, skin name... obviously it's the name shown in aurora to determine what skin it is and so on... however, "updateID" isn't relevant for the time being, it's not used for anything right now but it will be later on...
Here's a screenshot of the Generator:
