How to export textures from idTech 5 based games?

Hey everyone,

First of all, my apolagies if this is placed in the wrong section, I thought since you need to export textures aswel when exporting a model from a game, it comes down to the same in my case.
Anyway, I can’t figure out how to export the textures from idTech 5 based games, and then I’m mainly talking about Wolfenstein: The New Order and The Old Blood.

I’m in love with those propaganda posters/magazines/signs/etc and I want to collect them, but I can’t extract them from the game because I don’t know how to.
So, does anyone know what program I need to use to being able to read and export the files from the games so I can search for the propaganda stuff?

I’d like to know as well, I spent hours researching and trying different things people had posted on Xentax but to no avail

The closest I got was using the method by m0xf in this thread, but the tool doesn’t work with The Old Blood’s .exe
