I made these models just using WoW. Export, WoWModelViewer, Photoshop, Milkshape, MdlVis1.40 and War3ModelEditor1.07, so I am sorry mate I don't know. I made them when reforged version does not exist, about 2 years ago I think, and none .DDS files are included.
Sorry mate, I don't have any plan on night elf building for now, because I have to finish the human packs first. Maybe in the future? Who knows, I have to fix all the bugs of Kultiras buildings first. lol
I am using the reforged version, but I used these models before in the classic version WE. I check them last night in reforged WE again, they are still good, I may need some time to find out. Maybe I should to check them at another version of old WE.
