I don't know if it's just me, but I think the equipment texture is not mapped correctly, it's all pink.

I got stuck on this too. Even if it's no longer relevant to you, if anyone else has this problem, apply the texture Props_02_diffuse from the textures folder to the items in the equipment folder.
Edit: I looked at the provided photos and that's not the correct coloring, it just looked ok on a couple of the melee items. It's better than nothing, but that's not the answer.
I got lucky in figuring that out and I feel like that could have taken a long time to figure out, or might have required me to re-texture all the equipment items if I couldn't figure it out Hope to see that fixed in an update, otherwise it's a cool pack. At least from what I've seen so far. I did purchase the mid tier or I wouldn't be complaining stuff isn't 100% textured. Everything else I looked at seems textured correctly.
