Open Cities Skyrim is a comprehensive project that aims to bring back at least part of the feel of Morrowind - specifically how most of the cities were a natural part of the world and you could just walk in without loading screens. The added immersion and realism goes a long way, probably a lot more than you might think. Ever wanted to ride your horse into the center of Riften? Well now you can. Need to get some help from the city guards to vanquish a foe? Run toward the gates and the guards will do their duty while you can seek safety within the walls. The town guards make for some very interesting interactions this way. This will also make running dragon battles that much more interesting since the flow of the battle won't be interrupted by the loading screen and all of the city guards can be involved at the same time.
Skyrim Special Edition 188.8.131.52.8 or greater.
SKSE 1.6.9+ and SkyUI 3.2+ are required in order to use the in-game configuration menu. They are NOT required in general for the mod itself. It is safe to let this go until SKSE and SkyUI are ported to Special Edition.
DO NOT extract the contents of the BSA file into your Data folder as loose files, or let your mod manager peform an equivalent function on the contents of the file. Doing so will cause things to load in the wrong order and break the game. Skyrim is intended to load a BSA alongside it's ESM/ESP file. Circumventing this causes issues which I will not provide support for. If you insist on going against this advice, you will receive no support for the problems you generate as a result of this.
Installation - Wrye Bash BAIN
Drop the archive into your Skyrim Mods\Bash Installers folder, then install as usual.
Make sure the mod is active in the Wrye Bash mods tab.
Installation - Nexus Mod Manager
Use the "Download with Manager" button on the Open Cities Skyrim page at Skyrim Nexus. The installer should take care of things from there.
Then simply make sure NMM has the mod activated.
Installation - Manual
Drop the Open Cities Skyrim.esp and Open Cities Skyrim.bsa files into your Data folder.
Activate the mod using whatever management tool suits you.
Post Install Configuration
Set the mod's load order using whatever management tool you feel most comfortable with.
LOOT should set the proper load order, and is the recommended method for doing so.
It may also be necessary to rebuild your Bashed Patch if you're using one.
Once the game loads, you need to allow 24+ game hours to pass for AI to fully update in each city.
Uninstalling Open Cities Skyrim
Due to the nature of Skyrim mods, especially those adding scripts, it is strongly discouraged to attempt uninstalling a mod from your active game. Any mod that is more than pure mesh or texture replacements has the possibility to leave behind permanent changes to your save that you may not want. This is not something modders can correct for. It is how the game was designed by Bethesda. No support will be provided for anyone who uninstalls this mod from an active game and continues on with that save.
Open Cities Skyrim should be loaded as late as possible in order to preserve changes to navmeshes and other exterior city data.
If you are also using my alternate start mod, make sure that loads after OCS.
LOOT should be used for optimal placement.
Mods which strictly replace vanilla textures or the vanilla meshes are 100% compatible.
Generally speaking, any mod which adds things to the closed cities will be incompatible.
City mods that add some details to the open worldspace will be partially compatible.
The Last Defeat of the Dragon Cult - The mod hasn't been updated since March. It's navmeshes are partially corrupted and must be repaired.
More Dynamic Shadows & Striping Fix - Numerous dirty edits that cause some interiors to cease functioning.
Mods which edit the following scripts will not be compatible unless patched:
The Civil War battles which take place in Whiterun, Solitude, and Windhelm will be fought within the closed city worldspaces. This had to be done due to complications that were not possible to overcome with the scripting involved in the war and how it relates to several other quests. Expect load door transitions when a city battle is underway.
If you have a problem with an Open Cities mod and wish to report it, I'd appreciate as much information as possible, preferably in the form of a screenshot with console data showing if it's something that can be screened. The FormID of the affected object would help greatly to narrow down any problems that might result. Post this information along with your load order. Reports with less than detailed information may result in delays in getting it fixed, or result in being ignored entirely. It helps everyone to provide details. I am especially interested in verifiable conflicts, as I wish for Open Cities Skyrim to be as conflict-free as is humanly possible given the circumstances. If the situation requires a patch, I can only work something out if I know what to look for.
The doors inside Warmaidens (in Whiterun) are missing, what have you done with them!
The More Dynamic Shadows & Striping Fix mod makes a bunch of dirty edits in Warmaidens that will cause the doors to disappear. This mod has several other problem locations as well and it isn't recommended to be used in general until the author fixes the problem.
I am getting unexplained CTDs when using Open Cities with other mods. What gives?
Open Cities Skyrim requires the latest version of Skyrim Special Edition, Patch 184.108.40.206.8 as of the writing of this document.
Many mods have not been updated since their creation. The most likely causes of issues will be from mods that have navmeshes but have not had them properly redone using CK 1.6.89 or greater. These mods need to be updated by their authors or they will simply not be compatible with the updated navmesh formats and will cause CTDs in any configuration that includes updated mods.
When a mod is reported and confirmed to suffer from this problem, it will be listed in the Incompatible Mods section until such time as it is updated by its author.
Locations of AI Doors
The AI doors are entry ways into the closed wordspaces should it become necessary. Not everything that is placed in a city by a mod is worth the time it takes to create a patch. Mods that drop items for a one-time pickup are a good example of this. It's much easier to just go through the door, get what you need, then exit the city as normal.
Riften: East of the main city gate, next to the alley gate.
Markarth: Enter the city gate, turn immediately to your right. The small rock in the grass patch next to the ivy.
Whiterun #1: East side of the bridge into the city, right next to the brazier that is closest to the guard shack.
Whiterun #2: North side of Jorvaskr, on the side of the path up to the Skyforge.
Solitude #1: In the rock pile between the city gate and the executioner's platform.
Solitude #2: In the rock pile across from the Bard's College, immediately to the south of the manhole cover.
Windhelm: As you enter the city gate, turn immediately to the right, then immediately right again. It's in the bushes right next to the wall.
