In fact, a bunch of you have already jumped in and started modding the game. We have over 270 mods already uploaded to the site, with more than 421,000 unique downloads. These include things like a Simple Photomode, a new HUD, Better HUD, and the Ayleid Reshade, a preset created to bring back the vivid colours of the original game.
So, what do we know so far about how the game works?
As soon as the game dropped, we were all frantically downloading it here at the office, ready to poke around and find out how it all worked. However, less than an hour after release, the super-talented users in the community with a passion for reverse engineering had already cracked the game wide open and were discussing their findings, so we're keeping an eye on their conversations and supporting them if we can. Special thanks to doodlum, shad0wshayd3 and the other members of the xSE RE Discord server for providing us with a summary of what they've found so far!
Oblivion Remastered uses an interesting hybrid of two different game engines - a modified version of the original 2006 Oblivion game engine and Unreal Engine 5.3. If you take a peek into the installation folder, you'll actually find a large chunk of the original game assets still intact, including the original game plugin files.
Below are a few key things we've collated from our observations and what we've been hearing in the community. Take everything you read with the biggest pinch of salt at this early stage:
- The core data for the game is still loaded from the plugin files, as with the original games; however, each game object (record) in the plugins is mapped from Oblivion Engine to Unreal Engine using JSON. This means that the traditional methods of detecting conflicts may not work anymore.
- When adding new content to the game, the JSON data for this content would need to be inserted.
- The JSON structures for many game objects include additional values that did not exist in the original game, and the purpose of them is currently unclear.
- Any text that is added to the game via plugins seems to show up with an "[NL]" prefix, which is currently thought to mean "Not Localised". Investigations are ongoing to work out how to make mods that don't have this prefix.
- The new Unreal Engine versions of the textures, models, particles and animation files appear to still be linked to the original version in some cases.
- The Level of Detail (LOD) for this game appears to use a completely new system, most likely heavily controlled by the Unreal Engine side of the game.
- The game uses several scripting languages across different systems, including an updated version of OBScript, Unreal Engine Code, and Unreal Engine Blueprints.
- Concerning a possible script extender for the game (equivalent to xOBSE), there is a challenge of the Creation Engine script extender devs being unfamiliar with Unreal Engine and Unreal Engine modding being unfamiliar with Creation Engine script extenders.
- There are some hints within the game code that there may be a Construction Set coming for this game, but that may also simply reference the tools used by the developers.
- On the Xbox Game Pass store, the game states it includes "In-Game Purchases", which could imply the eventual integration of the Bethesda.net paid mods store.
- The Xbox Game Pass of the game came with a lot of extra debug data that is helping with the efforts to reverse engineer it.
- A version of xEdit is in development to support creating plugin files for Oblivion Remastered, but it is currently largely untested and not yet available on Nexus Mods.
To heavily summarise, there's some potential here, but unless we get an official Construction Set from Bethesda/Virtuos, there's a lot of reverse engineering work to be done before modding can be fully realised. Please don't badger the super smart folks working on this; let them cook.
Porting Permissions
One thing that is really important to remember when modding for Oblivion Remastered is that any porting of mods from the “old Oblivion” must have permission from the original mod author, either by contacting them directly or if they have stated this in the ‘Permissions and credits’ section of their mod page. It is also worth noting that it is unlikely that any of the old mods will work “out of the box” for this remaster.
What We Have Planned
We have already worked on the official extension for Vortex, which is up and ready for you all here, and there are plans to add Oblivion Remastered to the Nexus Mods app roadmap too once the modding scene becomes clearer.
Will It Support Modding?
At the moment, the official response from Bethesda on this is that no, mods are not officially supported for the game. They have stated that:
If you are experiencing gameplay issues while playing with mods, it’s recommended you first try uninstalling your mods, then verify your games files on Steam, or the Xbox App.
A big shoutout to Pickysaurus for his help on the technical part of this post. Let us know what you’re hoping to see modded for the game in the comments!

LET THEM COOK! :D
Also, since Bethesda said that no mods will be supported, that is only because they overloaded the game with junk (honestly, the reflections are way too sharp and bad and only raytraced thing appears to be light and shadows and reflections are rendered via some odd mechanics that makes your sword to have a reflection in water even though you are 300 meters away from it... complete nonsense to be honest and the reflection render is highly unnecessary and is also a performance killer for some people.
On the other hand, the game is in UE5 which is easy to mod so I do assume that people will just make mods work themselves like they always do... About the open interior mod, I do hope that someone or some group is gonna work on it immediately when they can. I would do it myself but I cant really spend time doing such things cuz it wont give me anything back but if no mod comes to surface within a few months up to a year, I think I may be able to do it myself... Its such a disappointment to see a game in 2025 that has more loading screens than Cyberpunk, KCD2 and a bunch of other games combined... Like legit, the amount of loading screens I saw in Oblivion within 6 hours, was like 1 year worth of loading screens... Cuz essentially I see one every 10 to 20 minutes when exploring and one every 1 to 5 minutes when in a city...
I'm not 100% sold on some of the choices Virtuos made here. Combat collision detection in particular seems really bad (Goblin face coming through my shield etc.).
Loading screens are hardly a major concern IMO and removing them would likely require a totally different game engine. The UE5 veneer used here is impressive but only skin deep, so to speak.
nm: you meant interiors, not the cities..........
Looking at the ui and Oblivion's nostalgia based assets, I'm seeing a huge amount of potential for modding tools to replace virtually everything about the way you play this game. I expect we have something amazing hidden under the surface of the vanilla game and it has
the potential to become one of community's favorite modding experiences. Of course that's after all the starting out modding prototypes
are refined and become standard tools for us.
Man I'm just thinking about how rough some of the nostalgia parts are in this game but I think it might be a blessing in disguise. Just think how much more it'll change when some of the major modders get a hold of them.I mean that character creator is sooooo simple, imagine
what the characters are gonna look like when someone refines them through modded racemenu's ui.
Also I'm seeing alot of the comments are more about worry over how the game will go considering the hybrid system between old and new era engines or about Bethesda's reservations about supporting mods rather than excitement over what mods will come out or how excited they are over having a new Elder's Scrolls remaster in the first place. C'mon though. Just give the modding tool dev's some time and they'll
figure out all the little bumps along the wayand before you know it we'll have a banger on our hands that's one of the community's new go
to's for modding goodness.
LASTLY I THINK SOMETHING REALLY NEEDS TO BE SAID AND I HAVEN'T SEEN ANYONE FOCUS ON THIS SERIOUS PROBLEM WITH THE NEW GAME.
That issue being no one started a comment thread of what mods ya'll looking forward to seeing!!! :3
Sooooo what mods are you guys looking forward to?
personally I'm a weeb who's stuck in between pushing the boundaries of how nice characters look and trying to make the game itself look as scary as possible.
What about you guys? ^.^
But first and foremost, I’d love to see my favorite quest mods again! Not sure if that’ll ever happen, though. Stuff like KotN Revelation, Order of the Dragon, Servant of the Dawn, Mannimarco Resurrection, Lost Spires, Nehrim 👀 - the list goes on.
I’ve been playing Oblivion since 2006, and the mods that came out in the following years are what made the game truly worthwhile.
Like Unique Landscapes, Better Cities, Creature Divrsity, Immersive Weapons, Armamentarium or Midas Magic Spells. With maybe a few npcs/armor mods from Skyrim like Apachii Sky Hair or Immersive armors, along with unofficial patchs and whatnot and I think it would be pretty much complete for me. Not sure how long it would take (nor if it will) to be at that state but I pray Talos for it.
One can dream, eh?
Seriously, though, I'm already trying to see what can be done to port OOO. It's not going to be easy, but maybe we can start small and build up as the tools get better.
It would be amazing to have a mod that adds several predefined shapes (different types of lips, noses, eyes, etc.) to choose from directly, without having to deform the models with sliders.
It would allow us to create prettier and more realistic faces, kind of like in Skyrim with all the character creation mods.
