Depending on the plugins you are using to create geometry, you can most always smash the modifer stack down into a simple geometry which can be exported as a obj file using the Habware plugin. Or, if you simply want to export a flat uvmap of the object, and you do have max, then you need to get the object texture unwrapper plugin from Peter Watje (it's on all the standard free max plugin sites). It will unwrap your UV coordinate into a usable bitmap. Drop me a line if you want more help with max.
