Wow, I'd never expect such interest in Rimmen.
Welcom to the team Auryga, I will need lots of help with everything. Expectations are growing very fast and its getting way too much for me. Actually you can become team leader if you like because you seem much more experienced in modding than I am (I haven't released a sigle mod so far).
I was thinking about a plateau around cell 12, -18, after some landscape edits there is almost enough flat space for Orcrest oasis district.
It's shape would be closest to rectangle and would be a bit larger than Orcrest oasis district but deffinitly smaller than whole Orcrest, but thats just an idea. We'll let you know as soon as we decide.
I assume this is going to be a completely separate mod, adjacent to Anequina? I don't use any of the terrain in the Rimmen area, so you won't have to worry about conflicting landscape edits.
I think Rimmen is supposed to be directly south of Bravil, just a little way off the Bravil-Leyawiin road, across the Elsweyr side of the border -- on the hillside with a view of the Niben.

Look at Tamriel exterior cell 15,-20: you'll find an initialy disabled map marker named 'Rimmen'. Same place as the word 'Rimmen' on the colored map 'cyrodiil_elsweyr'. This terrain is pure 'vanilla', as far as I can see, exept the marker of course

That location should correspond roughly with Bethesda's dot on the map.
I'll send you the textures when I get home in the evening.
Ok, i'll create a hill mesh (otherwise it'll look strange if the size of the walls changes, when the engine switches from _far to normal mesh)
It would be best if you and grzesiog1 decided together where exactly to put Rimmen. It would be easier for me then to create the wall meshes. If the city gets some sort of flat space to stand on, I'd go for different wall meshes than if the city has to be built into the mountain. The expected size would also be helpful.
Thanks.
I will try some more things with the landscape lod mesh as well. I created a copy of the Elsweyr esp so I can bash around the ground a bit to hopefully generate a better one. I think I will remove the roads from the LOD mesh as well, as I prefer the smooth-sided hills like in Cyrodiil. The LOD mesh over-emphasizes them.
Rimmen is grzesiog1's design so I leave that entirely up to him.
I got a question for the thread starter! Do I have to delete and reinstall or reinstall the ELSWEYR, THE DESERTS OF ANEQUINA mod to play the contents described by you?
The updates are simply dropped in your data file on top of the existing stuff. There is no need to reinstall the entire mod each time.
In any case, since tombs used in "the Necromancer" belong to the "Barabus Crypt Set" . . . Phitt's tombs I have not seen so I cannot judge.
I guess its up to Iliana and the rest of the mod contributors to decide what resources they would like to use and I am certainly not worried for the quality of the addons that will follow
take care
Its not urgent. I will just wait and see. I didn't plan to create any tombs till sometime in the new year.
