Hi! I'm getting critical error when i try to load the game with my edited L2UI_CH3.utx file.
The steps i do to create my file are the following:
1. I use l2decrypt to decrypt my .utx
2. I open it in unreal
3. I add the icons i want and compress them in DXT3

4. Then i encrypt it back with l2encdec with 121 encryption
I'm not sure but i think i do things as many guides here suggested but i still get critical error on game start so can someone tell what i do wrong here?

 

Edit: just to clarify things more i only get critical error when i try to edit the existing L2UI_CH3 file...If i create a new utx i have no issues.

Just use l2 tool to replace a file. Its easier.
