Unreal Engine 5.6 Released

General Announcements

I’m glad someone gets it. Its cool to buy into the hype and get excited about new things but to blindly defend behavior that erodes trust in something you love… well that’s not love. Flashy new features impress investors and shareholders… you know what doesn’t? Taking the time to finish and stabilize said feature before your asked what’s next. Anyone in this field whose been here for any length of time … let’s just say if you know you know.

This is a partnership where a company licenses you a tool. This agreement has a EULA and if you use this software within enterprise orgs … has comp support which also is billable. If the product is mismarketed or so unstable it impacts “your job” and “your livelihood” because your team/engineers are fixing core engine issues, then it fails to meet its “value” to you or your organization. If previous versions become as much of a burden to maintain or fix deprecated subsystems or modules then it’s also a risk you evaluate but should also be able to voice when the new “Major” version is struggling to maintain stability.

The alternative is a mass exodus without any feedback from “customers” of the tool leaving epic the out of basically saying “why didn’t you tell us” or “if we would have known” … Anyone with kids or any actual professional role understands this product → client feedback loop.

Ultimately even the “fans” will lose faith when all the professionals find the most efficient means to accomplish their goals. Be that by sticking with UE4 … heavily modifying a “more stable starting point like UE5.5” or swapping engines entirely. You have to hold things you care about to some level of accountability. The former is simply unprofessional and immature.

To say it’s your responsibility to “chose your engine or upgrade path” is repeating something every engineer understands and knows like it’s some issue to “trust” in something that is marketed as “production ready” which falls back into this accepted status quo I originally stated was a problem.

The problem isn’t that you trusted your business partner and the quality of their tool … the problem is the partner is becoming untrustworthy. So much so “you shouldn’t expect stability in a Major.Minor.0” is actually become the norm and anyone who expects better is ridiculed.
Might as well slap a disclaimer on every patch “release” that says you agree to be glorified QA testers, bug reporter or even the contributing engineer to fix core issues due to trusting a .0 patch release because according to the comments “it’s the understood state of things” and if your too new to understand this you’re a simp… like its already EPIC’s official stance.

New comers to Unreal Engine go straight to launcher → grab UE.5.6 and are met with issues. They then come to places like this and get told how “ignorant or dumb” they are for using a .0 patch of a major.minor and then preached to because they don’t understand the erosion and status quo… its sad … and honestly I’ve been in the epic camp long enough to remember times it wasn’t like this. We should all be demanding better and honestly should be practicing more empathy and kindness to frustrated newcomers!

20+ years in this year as an Unreal Dev/Engineer and I’m honestly embarrassed to read the attacks towards people asking for accountability. Any studio that has a partnership with epic and earns revenue has an invested interest in seeing this engines success. Plugins, Tools, Fab, Games and the “trust” in the product erodes and so does your ROI.

Don’t be offended or triggered by those who care enough to spend the time to give feedback… be offended and triggered by the professionals and engineers who simply stop caring enough to engage due to the above behavior and silently move on to other tools.

Let your love pride and your ego challenge you to instill the “merit and respect” your trying to defend in your product by “listening, adapting and empathizing” address the issue by true resolve not by attacking the messenger.

Thank you very much for this. Most people don’t understand this bitter truth and instead blame game developers for the engine’s faults.

Stop saying that is a developer problem if they upgraded to the new version, since they forced to upgrade with reason “old version bugs are fixed in new version”, but instead we get the old bug and new bugs, since the old version of UE wont get support anymore.

This is the exact issue I’m talking about. Lack of empathy for the lost value of the tool. Developers lose value by being forced to maintain and support deprecated versions or attempting to fall in line with EULA and move to the “last 3 versions” as required in EULA.

No LTS and quality issues that require time and effort from your team/company where the opportunity cost is lost on your project that otherwise wouldn’t exist if your project was being developed 4 years ago at the end of ue4s lifespan or during the last 3 versions of ue3.

You could pretty much grab 4.19 - 4.27 and rock with it without major core challenges. Stating an engineers job to access the risk of the results of said situation doesn’t somehow resolve the problem. Knowing the problem isn’t some glorious accomplishment and attacking people for calling it out to defend the current state isn’t a showcase of talent either.

Everyone who cares about unreal engine’s success should want every release to offer the most value it can to studios and enterprises that adopt it. They should be able to stand on merit and defend the software and its current status as newcomers flock in to grab the latest versions.

We should want the overall first impression to have lasting growth and value even from college students opening the editor for the first time. I consult with educators regularly and can tell you ….. it’s in our best interest to be better than we have been. Plain and simple.

What good does it do to flash fancy rendering techniques, promote new tooling and hype with the results being the fastest adoption rate the engine has ever seen across multiple industries only to leave the masses with a sour taste or give the first impression that the tool is broken and the truth is it will take “more effort and engineering time” to adopt it in it’s current state?

The mass appeal and hype essentially erodes as you learn the emperor has no clothes and that distrust becomes “reputation”. Newcomers get met with attacks from so called “veterans” and indies feel abandoned by both the engine and the “so called” experienced members in forums telling them to “suck it up … its your job”

I’m sorry but this behavior is unacceptable and does the opposite of support growth of our community and ecosystem.

I am also glad to see someone who shares the same view as me, but I believe it is with the continuous improvement and strength of new features in the UE5 engine that they have begun to develop arrogant emotions, Epic has forgotten its original goals and direction, and the huge success of UE5 has caused them to lose themselves, becoming indifferent to user use and experience. They have already started to care less, leading to the collapse and instability of the entire architecture of UE5.

It seems that UE5 has upgraded many new features, but the original old features are constantly collapsing and failing, causing users to gradually lose confidence in continuing to use it. Whether it is finding and identifying errors, or waiting for the new version to correct their projects, it has consumed a lot of time and money from users, causing great losses to every development team using UE5.

However, Epic It seems that they don’t care about this,they seem to think that these users have been trapped by them and can no longer leave them,this is the most ridiculous situation. So I think once some companies engage in these monopolistic business practices, which is the beginning of their decline, at least we have an Untiy engine to choose from. UE engine is not the only tool to monopolize the gaming world.

So I think Epic should recognize this as soon as possible and put the development of UE5 back on the right track as soon as possible. After all, the AI world has also begun to arrive, and there will be huge changes in both the film and gaming fields. Once AI tools achieve rigorous, accurate, and mature standards, all 3D tools will become worthless,

In case anyone runs into this, I never manually touched DefaultLightmass.ini in the past but I had an svn commit that said:

“add lightmass config (was autogenerated by something)”

In the config it had:

[DevOptions.StaticLighting]
bUseFastVoxelization=true
bUseEmbreeInstancing=true

In 5.6 (not in 5.5), bUseEmbreeInstancing=true causes a lightmass crash in UnrealLightmass.exe!Lightmass::FEmbreeAggregateMesh::PrepareForRaytracing()

Set back to false to fix.

But the engine should ignore the setting or warn about it if it can’t support it, especially since some engine stuff autogenerated that file in the past it will hit a lot of people.

235

Exactly. No one needs to upgrade if the old versions are updated for at least a year. But instead, they abandon old versions with bugs to push new releases, because marketing new features is what matters to them.

236

Frequent release of new feature versions is not a problem, but it is important to ensure the effectiveness and stability of existing features. However, in reality, existing features often encounter various unpredictable errors, which makes it difficult for users to use this tool safely. I have been using Autodesk’s 3D tools for many years and have never encountered such a frustrating situation，this is a ridiculous maintenance and development ability, as they seem to be playing with users

237

This release, as most of the 5.x releases, feels like the engineering dept. has been overtaken by the marketing dept. It’s all about getting as many features as possible on the list and enticing new sectors to increase growth.
We have been trying to upgrade our pipeline from 4.27 to 5 since 5.2 and every single release breaks VR rendering in new and mysterious ways preventing us from doing so. It fails to be resolved in a hotfix, instead waiting for the next major release - then that one comes, fixes the previous bug and breaks VR rendering a different way.
Not to mention since 5.5 they broke baked lightmap compatibility (if you build lighting in 5.4 or earlier, you can’t use it as is in 5.5, you need to rebuild it in 5.5) so in order to upgrade safely I need to duplicate over 100 projects so I can rebuilt lighting for them in the new version.
Now UE 5.6 breaks instanced stereo if used together with virtual textures (immediate crash).
At this point I am skeptical about every upgrading to UE 5.

Napimel,

The decision to adopt Unreal Engine and how to work with it; ultimately rests with the developer. Epic provides the engine, source, and documentation, but the responsibility for understanding its workflows and adapting to changes lies with each project team.

I’ve been working in UE5 since the start of the 5.0 Early Access (on a 200 GB, highly complex project). One thing that’s clear from experience: blind upgrades are risky. For example, 5.3 quietly changed how turning was handled and broke materials that had worked fine in 5.2, especially on older GPUs. In my case, marketplace assets using features incorrectly started crashing outright.

That’s why I keep multiple GPUs on hand — a 3080 for primary work, plus a 3060, 2080, and a Radeon RX 6900XT — so I can quickly swap and isolate whether an issue is card-specific or truly engine-related. It’s hard to fix something if you can’t even get it to run, and swapping hardware is sometimes the fastest way to narrow down the cause.

In my experience, most breakages aren’t Epic shipping a “busted” engine — they’re the result of code or assets relying on behavior that was never officially supported. If you approach upgrades assuming the fix starts with your own project and dependencies, you’ll spend less time waiting and more time shipping. More than once it’s felt like Epic was speaking directly to me: “Don’t use it that way.” An assert would suddenly be there that wasn’t before — and yes, Epic does review telemetry on usage.

As for calls for LTS — it only makes sense once the tech has matured. Nanite, Lumen, and other features are still very much novel technology, so “freezing” them for long-term support right now would stall that progress. Epic has always designed Unreal Engine for the future; keep that in mind as you upgrade.

Well let’s hope there is an Update tomorrow. Coming from 10 years of the Unity engine, I am used to silly promises that never arrive. But when major things are Broken like Steam Multiplayer, I become concerned. I have asked for a schedule multiple times from Epic. We should be told , “Hey we will post Weekly fixes.” But when asked for a schedule we get Nothing. But UEFN has been receiving updates. It is starting to make me feel like Standard UE people are second class citizens.

agree with that.

agree with that too. though my pov with LTS would be to have it alongside regular releases. so that way new features are still advancing while the rest of the engine can improve in stability.
i mean, ideally.
even if epic devotes less resources to an lts than a regular release it would be valuable to many. it’s also a possibility that the community could do a bit of work on that line.

on the other hand i do agree that from 5.0 the engine has been buggy, and it lowers the value of the tool and makes it harder to use. i do think it’s mostly because of nanite and lumen and other refactors are a big piece of work. stability has improved, but has been bumpy. it’d be nice if it keeps improving.

The good news is that version 5.6.1 has been updated, but the bad news is that we still cannot gather text during localization. The Engine.manifest file remains missing, forcing us to continue using the one from version 5.5.

242

Isn’t there a list of changes or any announcement thread for 5.6.1?

243

patience. They take a while to release but it should be within the next few hours

Hey everyone, here’s the latest with the 5.6.1 Hotfix!

Future notes to consider: Beginning with UE 5.7, Linux will transition from SDL2 to SDL3. Users with customizations to SDL2 code who are interested in switching to UE 5.7 should be aware that they will need to rework those changes for SDL3.

Looks like a lot of nice stability fixes, in particular around Metahumans. Will upgrade shortly.

Sadly, Instanced Stereo still broken. I’m sure it will get fixed in 5.7 in tandem with a different XR feature being broken.

Hello ,thank You for Fixes - any Eta for FastGeo/Transformers Replication ?

Nothing on Metahuman Wardrobe Items Thumbnails not showing correctly in MHC
And nothing on the terrible terrible destruction of Chaos Cache Manager not being able to Record Geometry Collections that had their Damage Threshold changed. This was working in 5.5
