Some NVidia textures for GS have returned. You can get them from here:
NVidia textures In an uncharacteristically responsible manner, I've tested out this stuff a bit more rigorously.
The first batch of files had a few oddities in it. Somehow, I had even managed to give Apts_6.3db the Apts_6.pcx texture, when, logically(?), it should’ve had Apts_5.pcx as a texture. That, and some other bone-headed mistakes have been fixed. Still, I can't promise that it's all kosher.
Most things in the .zip are NOT meant for ATI cards, but there are four .3dbs that can safely be used by ATI owners:
Silo_1.3db
hokmrtrt.3db
hokmrtrb.3db
UH60_H.3db
Small fixes for tiny problems. It’s likely that most folks wouldn’t see anything amiss with those .3dbs, or, if they did, they probably couldn't care less.
I’m easily annoyed by quite trivial things: little children with tambourines, and dogs with no eyes, for example. Don't get me started about adding pineapple to a pizza. That is worse than wrong, and you would most certainly suffer eternal damnation for such an action.
I fixed the RS for the Blackhawk to avoid scenes like this:

It may seem as though there's still undesired transparencies in the Blackhawk texture (mostly in the tail) but those are due to flaws in the .3db wireframe itself. I can't get at that directly, and it would probably take me several years to fix via hex-editing. It ain't gonna' happen.
It's a pity that WB never implemented any .3db support in 3dzStudio. It'd be a huge bonus to able to view a .3db wireframe with more than 256 elements; even if it was untextured, and even if one couldn't actually edit it.
If you have any problems with this stuff, please let me know.
