I'll be upfront and honest, I've followed this community for a few years, but haven't been very active. I'm mostly on Nexus. Despite that, I know there are a ton of extemely talented mod developers here, and I dare say the community is actually even friendlier and more mature than Nexus. That said, I'm in a bit of a bind, and I'm hoping someone can help me with my issue.

So I have about 20gb in total worth of loose texture files. Some are for the base game assets, and others are for modded items that have been added.

I've been extremely careful and organized when trying to pack my textures into a .ba2 file. It cuts the size from 20gb down to 13.3gb, which is pretty sweet. I have an esp to match the name of the .ba2 file as well.

Yet when I start the game, textures for modded items load just fine (such as food textures for Food Drive Favorites, and even weapons textures for the 10mm SMG and classic Assault Rifle)). Yet textures for base game assets don't seem to be loaded. For example, I have a texture that should make the inside of the house mostly made of brown wood during the intro...but even though modded textures work, the house walls are still generic white.

My .esp file is named exactly "Fallout 4 Ultimate Overhaul Texture Pack.esp"
and my texture file for it is exactly
"Fallout 4 Ultimate Overhaul Texture Pack - Textures.ba2"

The structure of the .rar I've packed them into starts with Data, and then leads to these 2 files inside of the Data folder.

Anyone have any ideas? This is pretty much the last stage I have in my project, and it would be absolutely dope if I could get this working!
