Copy the DAT file from D:\SH3\data\Submarine\NSS_Uboat21 to another location, just to be safe.
Then
open the copied DAT with
Pack3D and follow my instructions earlier.
I assume in the Geheimprojekt mod there are
TGA files? If so, you only need to
IMPORT them (into the
copied DAT file) by using Pack3D to swap the external TGA files with the ones inside the DAT.
Once the copied DAT file contains the TGA's (aka Skin files) that you want to use with GWX, create the following folder structure:
Lutzows XXI\data\Submarine\NSS_Uboat21\
Now put your new/adjusted DAT file in the NSS_Uboat21 folder you just created and you have a JSGME ready Mod.
