wow, you're a pretty damn good texturer to say the least! And wow, i'm Really liking that model :O impressive stuff
It's very easy to convert weapons to battle format, and if you want to do it for field too, its a little harder, but still pretty easy. for most serious FF7 model conversion, you're gonna need to get Pcreator, which is available from the qhimm wiki. once you have that, make sure the texture is at a resolution the game can take, else it will glitch up ingame. Convert the model to 3DS, and make sure there's only one piece of mesh data in each one, or else only one of them will load. and open it with pcreator. select the group you just added from the group selector up the top. now sometimes the .3ds already comes with a UV, so you wont need to import one. but if for some reason it doesn't come with a UV map, you gotta import one with the "import UV" button, which you can export with 3dsmax, and i'm guessing blender too. once that's done, choose the open bitmap option and find your texture. for battle models, go to options and tick battle model. then hit the "texture file(s)" button. you're almost ready to export now. if the textures look flipped, go into UV Coords and flip 'em back. then hit save as when you're done. The buster sword's battle model is named "rtck" with no filetype, and if you hit "texture file(s)", the Textures should convert to FF7 format along with the model. then all you gotta do is repack the battle archive with the new files, and you're away. when you download apz'
buster sword (not sure about his custom cloud model), you get a pretty good tutorial on how to do this, so it shouldn't be a problem. hope that helps
