With the Floor Tiles Kit, I have now uploaded all the textures from this source that I intend to. AFAIK there is just one texture that I haven’t uploaded and I simply can’t see a use for it and I’m not sure it would work with NwN EE anyway.
Note you may notice that quite a few of the textures only have diffuse and normal maps. It might be an idea to use something like the add-in filter “InsaneBump” for gimp on a copy of the diffuse texture in order to see if you can create specular and other maps. I didn’t do this as A. I do have a life and B. The library was a big enough upload as it is.
