Ok, how it works for me
1. start umod AS ADMINISTRATOR
2. in umod: Main -> Add Game: ...\Tera\Client\Binaries\TERA.exe
3. in umod: Main -> Use Global Hook
4. Start the launcher. just the normal way, and start tera. umod should now show some options
5. in umod: Open texture/package -> load any of the *.dds file
6. im umod: Update (reload)
7. ingame: options -> video -> texture resolution: change the value from 1-3 randomly. after a couple of times, you should try some "combinations", the texture should be loaded.
unfortunately ive got no desktop recording program. otherwise i would make a small how-to video. fraps just records fullscreen applications like games :/
[:EDIT:]
okay, camtasia is installed, ill make a video and post it here as soon as possible!
okay, video is done. just got to upload it now....
