Howdy @Ironbelly! First, thanks for the reply and effort to show that, but I’m aware of this procedure and unfortunately, that was not exactly the problem that I’ve mentioned.
If you went ahead and tried to export either MET or RGS textures, you’d see that you won’t be given the option to save them as TGA but only “COPY” or T3D" instead, which are sort of “legacy” formats. They cannot be used with Photoshop or equivalent software, as they are not image files. The other textures from this pack (and many others) can be exported without problems though.
I hope this clarifies now. So if you could please take a look and see what’s going on, would be super cool!
Thanks again!
