[Baron Munchausen]

Organic and Crystalline ships (including units) are seperate hulls with seperate entries in the config files. In the default set they are using the same models and textures as the standard hulls. So the organic and crystalline races have 'distinctive' styled ships and units even before they have researched their respective racial techs. But this doesn't have to be the case. You can make ordinary 'technological' models and textures and dedicated organic or crystalline models and textures for a given race.
