"underground_station" and "underpass" have exact the same texture files in

res\textures\models\mus\albedo\ vs. res\textures\models\entry\albedo\ - only one more file in "underground_station": sign_border.dds
that's 14.1 MB

res\textures\models\mus\gloss_ao\ vs. res\textures\models\entry\gloss_ao\ - all the same
that's 12.67 MB

res\textures\models\mus\normal\ vs. res\textures\models\entry\normal\ - all the same
that's 17.33 MB

res\textures\models\mus\op\ vs. res\textures\models\entry\op\ - all the same
that's just 302.43 KB

res\textures\models\mus\uv1\ vs. res\textures\models\entry\uv1\ - all the same
that's 69.33 MB

the main textures folders res\textures\models\mus\ vs. res\textures\models\entry\ got the same small file: emissive.hdr
that's just 2.5 KB


The res\textures\ui\construction\ folders also got a few duplicates, but that sums up to less than a MB so scrap it.


So, as the mod "underpass" is a dependency I suggest to let all textures stay in there and just use references to those textures in "underground_station" to save the game process of managing an extra of redundant 113.73 MB of exactly the same textures.

And a lot of .mtl files of course are also duplicates - just with the different path in them ("mus" vs. "entry" in the path).
