And they busted my old "hack"
The attached xml file will remove fog from all the EQ2Map provided maps as well as many of the SOE provided dungeon maps (however like GM9 pointed out for many of the maps it is hard coded e.g. velious)
Just copy the file into uifoldername/eq2map/ folder and overwrite the existing file. Might want to add it to the ignore list in the updater as well
Note: I don't know what the result will be when a new map is added to EQ2Map; it will probably have black fog over it until the imagestyle is manually added to the attached file.
