I can't screenshot within Steam games for some reason but it's just the original Etti IV.
No, they are just in the override folder as is. No sub-folders.
I don't have any other mods installed. I put them in the override file by extracting them.
I put everything in there.
I did get an alert of an "invalid bump map" called "Dxn_Tmp2b.tga" while on Dxun.
