The buoy file and the nav file have an aweful lot of similarities in the way they are set up... But I can't seem to find any .boy(b) files for the XML1 maps anywhere. I haven't been able to walk around in the XML1 map yet, even with the .nav file in place. I have no idea what this .boyb file is used for, or how important it is, but I figure if it looks close enough to the .nav file, maybe it also is needed to define where you can and can't walk?
EDIT: Dammit, all maps also need to have a package file which defines all scripts, convos, HUD heads, models, XMLs, animations, skins, effects, textures.... If they had everything that defines a map in one folder, then that would be fine, but there are pieces spread across several folders, and you have to fill all of those in, synchronize them, etc. This is too much. Seriously. For one map, this is too much. Do you have ANY idea how big of a project this actually is? Does anyone know how long it took Raven to make XML1? Yeah, figure about twice as long for us to port their work, at least. I.E. not going to happen. There's simply not enough people working on this.
