Missing .nif and .tga files

[SlyElite23]

So, I'm trying to make a mod that includes a quest where you can change the Wraithguard to medium/light armour. When I double click on the Wraithguard in the objects menu of TESCS, I can see that it has an art file (a\A_ART_Wraithguard_GND.NIF) and an inventory image (a\TX_Art_wraithguard.tga). However, when I go to make the light and medium variations of this, and I go to select an art file and inventory image, I cannot find these files anywhere. I'm pretty sure that a few other .nif and .tga files are missing too, but it doesn't show when I play. Is it possible for someone to send me their Meshes and Icons folders for download, so I can find the required files?

The meshes and textures aren't missing, they're just packed in a BSA-archive called "Morrowind.bsa". To be able to point to a certain file in CS, you must extract that BSA-file with a program, like BSA Unpacker, into the "Data files"-folder. However, an easier way to achieve what you want would be to duplicate the Wraithguard-object (by renaming the ID and select "Yes" when CS asks you if you want to create new object) and make your changes from there.

Thank you for your help.

This is something I've been wondering as well. Thank you!
