Good lord, do I have stories to tell about this mod. Every now and then I get a little bout of megalomania and think "hey, they've been taking eons to do this, surely I could to it - and do it faster - if I just lowered the quality standards a bit! Say, back down to Bethesda levels, that's not a bad metric." There used to be a video on their forum showcasing all the provinces in OpenMW. The bulk of this stuff at the moment is just very cleverly designed heightmaps imported into the game via TESAnnwyn, which is a real bastard of a tool to use. This video was privatized, and I can tell you exactly why: because if I could figure out how to reverse engineer the heightmaps from the video, some other schmuck could too. (Note that the provinces in the screencap at the start of the thread are either flattened or chopped up in areas that are highly unfinished, like High Rock.) As I figured, Morrowind renders the height data (if in a somewhat simplified fashion) for its world map, so it's really just a matter of calculating how many cells the map consumes (the assumption being that one map marker equals one cell) and importing an appropriately leveled heightmap into TESAnnwyn using the resulting figures. I was able to duplicate Black Marsh this way, but after a solid two weeks of banging my head against TESAnnwyn's archaic documentation, I flat out gave up because I couldn't move it into an appropriate position.
Tamriel Rebuilt's another story entirely. These modders are highly protective of their assets, so unless you're part of the team, there's always going to be *something* you aren't privy to. Eight years ago (give or take,) that "something" encompassed anything that wasn't considered a "public release." This was back when Sacred East had just released and they were entering a kind of developmental drought in terms of public releases. They had that embarrassing teaser trailer for Almalexia with the ordinators dancing in the empty streets, so I figured they had a massive amount of playable content that was just behind closed doors. I was right, but the trick was in unlocking the doors. I figured interior modding would be the easiest way in, because I had no way to guarantee my writing would meet their Ascendant Uber-CHIM Loremaster standards, and exterior modding gave me the willies. I made a real banger of a house, but the thing with their interior modding review process is that they require you to use DE_Poor furnishings, which have an uneven surface. This is partly to ensure you're a bad enough dude to properly stack a shelf, but it's mainly just a fucked up hazing ritual to make sure you're a team player who's willing to meet their quality standards, because no matter how many times you think you've placed that motherfucking bowl evenly on the table, you're bound to get the claim sent back to you because it's just two pixels off. The real hell of it? They don't actually require you to use vanilla DE_Poor furniture on the project, they made their own copy of it with an even surface.
In any case, I got on board their team, and I was able to access their files, which basically entailed everything you can download from them now as the "public alpha release" or whatever they're calling it now, and everything else they have clanged in to their claims forums (Almalexia, Southern Morrowind which is mainly just a big empty void with Narsis in the middle) and after disseminating the files to some friends for review, we were both impressed and disappointed. Western Morrowind was visually impressive, but very frequently confusing to navigate. And while I'm usually wont to chalk that up to the project simply being unfinished, all of my experiences with the eastern half were disturbingly similar - huge, empty spaces with very little to indicate where to go or who I should even be talking to. Necrom, an area which is supposedly a gigantic pilgrimage destination for literally every Dunmer who respects the dead, is nearly devoid of people. Folks in this thread have praised this mod's questlines, and while I'm sure they exist, unfortunately all I ever seemed to find was trash mobs, scenic vistas and NPCs who didn't have very much to say.
TL;DR I'm a fucking maniac who pulled a retarded Ocean's 11 heist on a dumb internet forum because I couldn't wait like three more years for them to release their unfinished mod, mod world seems too big, needs to be fleshed out to work
