technical question: editing pre war clothes

[DeadSomething]

hi, i wanted to edit/replace the prewar clothes and came to some complications:

the dirty and clean versions of most prewar clothes share the same mesh but how are the textures bound to it?

i could only find one texture entry and it usually points to the clean texture, but how does the game load the dirty texture and how can i change that?

like if i replace them with another mesh, one version wont work and can crash the game.

can someone help me?
