To work with PSU, you will need to use a PSU client without Gameguard - PSU V1 - ]PSU V2 (else Gameguard will block TexMod) and to rename "gameguard.des" to another name like "_gameguard.des."
To extract a texture :
- With TexMod, in the "Logging Mode" tab, choose the no gameguard PSU executable.

- Set the differents parameters
- Click on Run, it will launch the game. Choose offline game.
- In game, go to the area of your choice and use + or - to choose a texture and Enter to extract it.
It works fine, I extracted some textures of the HUD, character (here Ethan) and in Parum:





TexMod can patch too the textures of a game so it's possible to modify a PSU texture and to use it in PSU Aoi offline. There is a good tutorial here for Tomb Raider to learn how to do but it's the same process for PSU.
Another tool [WORM] BustR found : 3D Ripper DX. This tool can extract frames, shaders and textures of PSU.





It's the version made by FaNaTiC.
