Как выбрали экспортируете фаил в папку с фаиломи от CMD
Запускаете cmd.exe и пишете pacextract.py и свой фаил в моём случае pl000.pac.
Жмёте Enter.
Заходите в папку pl000.
Потом в папку pl000_000.
Там будет четыра файла.Один .INDEX и три .tm2.
Открываете image studio.
Загружаете текстуры и редактируете так ка вздумается.
Не заменяете текстуры а сохроняете отдельно от них.

Запускаете Hex Editor.Загружаете сначало изменённую текстуру а потом стандартную.
На изменённой нажимаете Ctrl+A потом Ctrl+C
А на стандартной Ctrl+A потом Ctrl+V.Жмёте Save не Save as а Save.

Сново входите в CMD и пишете ptxrepack.py pl000_000.
Enter.
У вас появится .ptx.

Сново CMD и пишете pacinject.exe pl000.pac pl000_000.ptx 000 NEW_pl000.pac
NEW_pl000.pac перемещяете в другое место и и изменяете на pl000.pac.

Запускаем AFS Explorer ин наш фаил GData.afs.Перемещяем наш фаил в AFS Explorer и кликаем да.

Потом фаил GData.afs изменяем в GData.pak.
Конец работк.

Если вы всё сделали правильно у вас должно работать.

Если когда вы всё сделали и поменяли на .afs у вас не появилось GData.afs а появилось просто GData то у вас просто Windows не отвечает на запрос.
