I've tried to include a pair of previously created Wonders in my mod, but they haven't been built correctly, and so the NIF's don't display in-game. Neither in the City Screen, 'Pedia, or main map. I downloaded NifSkope, and tried editing the two offending Wonders, and when I opened them up, I could see the shape of the structure, but it had no skin. Just plain white.
So, I fiddled around a bit, found the Auto-Detect Game Paths (which got all the other NIF's working), tried re-saving the DDS files through a couple of different programs (trying to make sure the Alpha-layer was included properly, with no MIPs), and finally just renamed the DDS files. Which worked.
I have no idea why, but it worked.
Kinda.
It took some more fiddling and futzing to get the DDS to load for one of the Wonders (didn't like the first rename, renamed again, loaded). But, the other one (Sphinx) still doesn't show in-game. The 'Pedia shows a mostly blank page, displaying only the blue box with the Build Icon in the top-left corner, but nothing else. Loading up a savegame from before the Sphinx had been built, still nothing in the City Screen. Trying to load up after that Wonder had been built caused an insta-crash. So, though whatever I did made the skins visible in NifSkope, CivIV really didn't like it... But, oddly enough, though I did the same thing to both, Scool of Confucius now shows properly. I can't check if it displays correctly in the City Screen or map though, cause right now, as I said, the Sphinx is causing a CTD.
Attached, please find the art files for both Wonders. The #2 NIFs are my attempts...
Thanks.
