After almost 3 years of development, we’re thrilled to release OpenMW version 0.49.0—our largest and most ambitious update yet! Grab it from our Downloads Page for all supported operating systems.
This new release brings a hefty number of additions to our Lua scripting API, further polish to every single area of the engine—animations and lighting in particular—and it is the first one that goes beyond Morrowind!
The release announcement video by the tremendous Atahualpa and the stupendous johnnyhostile is entering its final stages of production, and we’ll let you know when it’s ready—but for now, be sure to read below for the full list of changes.

Good morning, who are you, and how are you today?
Hi! Name’s Maksim, also known as Max Yari.
I currently live and study in Germany. I have a past professional background in web development and a long-running semi-passive interest in game design. My current professional interests lay in the vague direction of some weird interdisciplinary scientific research in Biology, Psychology and Arts.
For the past few years I’ve mostly been busy squinting hard at the question of “So, what do I really want to do with my life?” as well as coding, making music, and wasting time.
How am I doing? Well… not too bad, actually.

We’re alive! And we’re continuing the previously announced testing of release candidate (RC) builds for our upcoming 0.49.0 stable release while our video editors are hard at work preparing a recap for the years behind us.
It’s been a bit, so as of the time of writing this we are up to round 5 of RC testing. Like before, you can grab the most recent RC build of 0.49.0 – or 0.49.0 itself, should you be reading from the future – from our GitHub releases page for all major platforms, and like before, we’d love if you tried it out and reported anything odd/interesting you might find to our issue tracker or 0.49.0 forum discussion. Or, at the very least, if you’re already daily-driving an RC, upgrade it to the latest build available for your platform, so that you can’t run into problems that we’re already fixed.
For example, Steam Deck players should update from RC builds older than RC3 to fix audio crackling. Newer builds also include various crash fixes and make the experimental precipitation occlusion feature work when sky blending is disabled.

In this blog post, we would like to address some questions that are frequently asked by our Discord and Reddit communities regarding 0.49.0 and the RC testing process.
Q: What’s so great about this 0.49.0, anyway? Is there a changelog?
A: 0.49.0 will be our largest release yet, having been in development since August 2022!
We are preparing a comprehensive changelog and a release video for the full release announcement.
Historically, RC builds didn’t get them, as they are subject to change. You can, however, get a decent idea of what 0.49.0 will include by glossing through the CHANGELOG.md file included in some RC packages and available on our source code repository. While it’s far from covering everything, it’s plenty – take a look!
Q: Is updating an RC build to a newer RC build or 0.49.0 stable release mid-playthrough safe?
A: Yes, it is! You don’t have to restart your run and can keep playing on the same saves.
Q: Is updating from 0.48.0 to an RC build or 0.49.0 mid-playthrough safe?
A: Very likely! You can definitely still use your 0.48.0 saves.
However, some modding areas are sensitive to backward compatibility breaks. More specifically, you need to be careful to update your mods that rely on OpenMW-Lua and any mods that touch our internal assets: MyGUI layout files and so-called core shaders (built-in forward pass shaders), not to be confused with post-processing shaders. Whether updating a mod that affects game content mid-playthrough would be safe depends a lot on the mod.
Do keep in mind the reverse isn’t true. You won’t be able to load 0.49.0 saves in older releases.
Q: Is updating from a release older than 0.48.0 mid-playthrough safe?
A: Probably. 0.49.0 preserves support for saves from all releases since 0.45.0 (March 2019).
If your old save fails to load or has problems for some incomprehensible reason that isn’t because it was made in a release older than that, you’ll want to tell us. If it’s merely an old save, you should be able to make it compatible by re-saving it in 0.48.0, which should theoretically be compatible with every single stable release OpenMW save ever made.
Q: I’m still running Windows 7 (8, 8.1). Would I be able to run OpenMW 0.49.0?
A: We do not provide support for end-of-life operating systems, so unfortunately, we have to encourage you to update to Windows 10, 11, or a modern Linux distribution.
While OpenMW is a reimplementation of Morrowind’s engine which itself remains compatible with any Windows OS since Windows 2000, OpenMW targets modern hardware and software, and while we understand that Windows 7 in particular was a hugely successful Windows release, it is a Windows from 15 years ago.
Note this isn’t a new change. Like Microsoft, we dropped Windows 7 support 5 years ago .
Q: Why is running OpenMW on a Mac so rough? Is 0.49.0 any better?
A: OpenGL applications like OpenMW are expected to remain in a bad shape on Apple hardware out of the box due to Apple’s deprecation of OpenGL support. Notwithstanding, we’re doing what we can to not make it rougher.
Q: 0.49.0 changes the combat and I don’t like it.
A: Well- wait, that’s a statement… Could you rephrase it as a question?
Q: What’s with all the talk about hit detection changes?
A: Yeah, that’s better.
0.49.0 makes some large steps towards making melee combat reimplementation accurate to Morrowind. Importantly, it moves melee target evaluation from the point of impact to the moment of weapon release. This is necessary to ensure the correct audiovisual feedback for missed hits.
We do not intend to meaningfully overhaul or redesign the classical experience of Morrowind, and we believe it would best be handled by mods from the community. It is currently planned for combat dehardcoding to be a focus in 0.5X releases, which would allow scripts to overhaul it, and for certain combat AI changes to be introduced to further ensure melee combat remains as (not very) challenging as in Morrowind.
An important detail to note, however: in RC4 and later builds, like in 0.48.0, the target must be within weapon reach upon impact for the hit to be successful. This means that dodging attacks by quickly backing away from the opponent remains possible even if the hit is evaluated as a success upon weapon release. This is consistent with Morrowind.
Anything else? Hm… No, that’s about it, really. Keep an eye out for newer RC builds! We’ll pop back up when we have more RC or release news to share.

Your patience has paid off, and we’re ready to start the process for the next OpenMW release, so are preparing our first round of Release Candidates (RCs for short). RCs are very similar to our release builds and are meant for testing – once we’ve ironed out all the creases, cleaned off all the grime, and bleached all the stains, one of them will become the next release. To do that, we need our users to find the problems, so we’d be very grateful if you took one of our RCs for your preferred platform out for a test drive and report any findings you make to our GitLab issue tracker. Please make sure to check first that whatever you find is not on the tracker already and that you’re running the latest RC.
If you just want to use OpenMW without hassle rather than test things, we’d normally say you’re probably better off waiting for the actual release or grabbing 0.48 from our downloads page. However, we’re aware that this release has taken a while, and plenty of Lua mods require something newer, so trying the RC will probably be more reliable (and helpful for us) than using a dev build.
Thank you and we’ll see you again on the day of the release!

S3ctor is a core developer of OpenMW, and has, like most of us to be fair, odd interests. This is the incredible story how he mixed two immensely cool things: Quake, and Morrowind, narrated by our hero himself!
Possibly the first thing anybody who has met me in person will say about me is that I am obsessed with game engines – and while OpenMW is my baby, my first love was idTech. At eight years old, I picked up a steel-book copy of Doom 3. Surprisingly, I ended up spending more time with the extras than the game itself. The developer documentary and Carmack’s E3 talk about the render pipeline and engine design captivated me completely. I have distinct memories of my young self barely understanding Carmack’s Reverse. I tried to explain it to other kids, to absolutely no reaction. Nobody else really understood, but it was the coolest thing in the world to me. All of this is to say that I have been interested in this technology since before I could read.
What we’re going to explore today is the history and process through which I developed a brand-new workflow for the OpenMW engine that allows modders to utilize arguably the most powerful component of old idTech – the brush-based level editor.
