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!

Bethesda never share their secrets with "thirds party" companies like Virtuous.
I think there was a contract with Virtuous to give them Oblivion 2006 Old source code nothing else.
Virtuous added the Unreal 5 Graphic layer while the game remained the same with its old buggy engine.

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? ^.^
Now loading/enabling *any* mod using Vortex crashes the game on start up, giving a "EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000050" error.
Only way to resolve this so far is to disable all mods, then do a verify files (using steam here).
Not sure if this is an issue related to Vortex, an issue with NVIDIA drivers or an Unreal Engine 5 issue.
Wondering if anyone else is having this issue?
Thanks.
Thought I had a bad mod. Uninstalled all, didnt work.
Do you think a particular mod caused this issue? Did you test running a single mod after the file verification?
Just the fact that I enabled any mod was enough to stop the game working with the mentioned crash exception (code 50).
Then uninstalling all mods still didn't resolve it - i had to so a full repair again through Steam.
I can only assume there is something that get changed as a process of enabling any mod via Vortex - could this even be the act of it changing the mods list that Oblivion loads? no idea.
Either way, I am stuck playing vanilla right now, which is a shame - Was really looking forward to using the mods!
Note: I have successfully loaded a reshade (not done via Vortex), which has had no issues at all.
Thanks for the feedback and hope things can be fixed somehow soon.
There is no anti-cheat and also no always-online data collection.
like as in Copy n' Paste work.
so really lucky, or unlucky... just as APTYaya said... Hybrid Frankenstein ass engine.
Mashing gamebryo into unreal engine is a lot easier than writing an RPG engine from scratch.
