this isd is already free to download somewhere, since it is an old mod created originally for fs1 (and it means it's a bit crappy), it isn't our job our isd is -or so I hope- in progress.
the xwing doesn't have lods so far, right, it's something i'll have to fix one day or the other, and I also want in future to make a destroyable rotating r2d2, and change few things in it's geometry, but for the moment I prefer to focus my efforts on new things, like that damned corvette, wich is the more painful ship I've ever made (but that will also result in the best looking one:))
