if you are interested in the modding topic of this game, I can share my information on vk, if you are there.

To edit textures, I used GIMP, or you can use Adobe Photoshop
No program was needed to integrate the textures.

Anyone who really wants to understand how it works, will explore the modification and will make his experiments.
I was able to change swastika flags, weapon textures, the MC's jacket, enemy textures, and posters
I once managed to insert custom sounds for weapons, but after the PC crashed, I was unable to recreate the method. Before the breakdown, I maked many experiments and manipulations during which I still replaced the sound

Bellox902, who created extractor v0.2, has not tried to improve it for a long time. He knows the id tech 4 engine well
I just started to understand this engine without programming skills
It's a pity that he didn't share the source code of his extractor for other people to refine it.
Maps and scripts cannot be created without the developers SDK.
However, I was still able to insert my textures, but not the HUD elements.

based on "workaround", can still do something interesting. I have plans to post more mods, but at the moment I am very busy studying
