I want to make the SW "end-of-the-world" gate (just past Falkreath and Halldir's Cairn) the entrance to my city's worldspace. Is there a way that I can grab a chunk of the existing valley just on the other side of the gate, then use that as the base landscape for my town?

Sorry if that sounds funky - im heavily medicated at the moment.

Hey!

I've reserved that spot for my mod!
(And Elinhir, the Hammerfell-town just beyond the pass, might very well be the next.)

To duplicate a cell you need to do it manually, I created a new worldspace using Tamriel as base (Use Land Data checked), then copy-pasted everything from the area around that pass into my new worldspace (using "Edit/Paste in Place") This map with coordinates helps a lot: http://skyrim.nexusmods.com/downloads/file.php?id=2251

I first marked the land I wanted to copy on that map (http://mods.jo-ge.net/sk/img/hk/hairan_keep_worldspace.png) then started to select all objects from all cells in one whole column, using the cell-view window, (holding ctrl). Pressed Ctrl+C to copy them and then switched to my new Worldspace and used Ctrl+Shift+V to paste at the correct coordinates, took me about half an hour for 11 x 11 cells.

To link the new world to Tamriel I put a pair of auto-load doors just on the opposite sites of the gateway in each worldspace. It works for now but I need to use a trigger and a teleport-script later so that the player can pass the gate on horseback.

This is how I started:

This is how it currently looks:

Well nuts - I was afraid if I didn't get started sooner someone else would grab the spot . A major plot point in the quests is that the town is the major trading hub between Hammerfell, Skryim, and Cyrodiil, and that was the closest I could get to where the Oblivion version of the mod was (it was actually up in the mountains near the Hermaeus Mora shrine).

Ah well. Thanks for the advice, tho - appreciate it.

Well, it's not like either of us really has a right to stake out an area for himself, but how about a cooperation?

By lore your trade hub would be http://www.uesp.net/wiki/Lore:Elinhir on the other side of the mountain range

I have some plans for city quests, but if someone does the tiresome work of actually building the city all the better

My current WIP plays in the no-mans land between Hammerfell and Skyrim. The cyrodillic baron who resides in a former (pre-empire) border-guard fortress apparently sent some raiders to a settlement outside Elinhir (I imagine a walled city and outside the city limits a semi-permanent settlement of war-refugees that can't affort to live in the city and merchants/caraveneers that want to avoid the taxes) due to the political situation, the keep's lord is currently untouchable by legal means, so the spokesman of the robbed people hires the player to "retrieve" the stolen goods.

My worldspace ends with a bridge over a ravine and a http://mods.jo-ge.net/sk/img/hk/signs.jpg. Halfway over the bridge, the player will get the "you cannot go that way" message. So if you start to work beyond the pass (SW of -22/-34), we could link our mods later. And if I go AWOL, you still could link your mod to Skyrim by detailing out the mountain pass area.
