I wasn't expecting Yokuda and whatnot to be done too. Pretty impressive.
I know it's early, and I assume you were probably planning this anyway but I think each province should have someone to organise the maps, what to claim, what to place there, do's and don'ts etc. where to download required files etc.
I also agree reading earlier posts - the amount of files coming from different modders will create inconsistency if it's not handled right. I've worked with large scale projects before and it's quite a problem - and the more modders, the more potential problems. I might sound negative, but I imagine it becoming the case.
I'm also someone who'd prefer to fixate on one area, finish it well, and then do something else. If I helped in some way with this (which I'd love to), then I'd rather join an area that already has significant interest and a strong, dedicated small team of modders. I've modeled and textured before, but all in TES4. That could be a problem for me as it's a step backwards in some sense, but I understand that TES3 is less complicated in a number of ways.
Ha, its not that impressive really, it's just a matter of trail and error
And yeah, the idea is, that each region is taken by a different group and they work on that and converse with the other groups to share resources, ideas and whatever.
And yes, one of the biggest problems is maintaining a set structure of datafiles, and not overdoing it, obviously, pretty much every other region apart from Morrowind will use mostly non vanilla objects as they just wouldn't suit.
Also, if your interested in joining, there are already a few projects up and running, starting to get alot of stuff done. Theres Province Cyrodil, Skyrim - HOTN, Argonia, Tamriel Rebuilt and recently started Hammerfell and Summerset Isles
And in a way its easier modding for morrowind, and in some ways its a bit awkward, modelling is anyway. Ive been modelling for years and recently started for Morrowind, but texturing for Morrowind is a pain in the ass compared to what I do for my own work
