Thanks again
@apathy for the database. I'm a klutz at manual updating this one, so I'll not touch it. Some of the newer files still drop the fatal error:file not found when trying to 3D view, but I have managed to workaround that by using ue viewer stand alone.
For those who want to use ue viewer by itself because of those outfits that give fatal error, once you open it and set the path the upk files are in, you then have to check the override box and select UE3, Blade and Soul and PC from the drop down menus. The program will take a while to load (minutes on a slow PC). It will eventually show you all upk entries in a new GUI window. In One Click Tool, select the outfit you want to see and note the skeleton upk number, then go back to UE viewer and search for that exact number.
Again, this is only if you need to view the 3D model of an outfit and the One Click Tool is giving you an error. If all you want to do is swap outfits and you already know what you are swapping, you won't really need UE viewer.
