I am trying to create new fxsxml files or modify existing ones. I have been looking all over the forums, and all the references I can find about this have a broken link to some program. I have been trying to use Nexus to do it, but I can't seem to figure out how to make a new file or to edit existing entries in one I load. Does anyone know of a working program that can do this, or is there a proper way to do it in Nexus?
