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: ```auto [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. ---

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. ---

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 ---

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. ---

Nanite, Lumen, and other features are still very much **novel technology** , so “freezing” them for long-term support right now would stall that progress. 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. ---

@Tina_Wisdom Sorry to ping you here, I’m a young developer and I’d like to contribute to reporting bugs I encounter while using Unreal Engine. Should I post this here, or use this “Unreal Engine Bug Submission Form”? ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/5/6/d/56d5fafc65b6530847322ae6710948930188a72f.png) It’s actually a small problem: All the links in the Help button in the game engine take us to the documentation for version 5.4 (and not 5.6), regardless of the option chosen. And regarding the documentation, there are many elements that are still outdated, sometimes even invalid C++ code examples. Are you planning a major review soon? And also to supplement it with more detailed examples to always make things easier for young developers like me? It’s sometimes annoying to have to use Chat GPT a lot or search through numerous YouTube videos to get information that can’t be easily found in the documentation. It would also be great to see all the old videos on the Unreal Engine YouTube channel updated regarding each tutorial and feature. Fingers crossed 🙂 Take care! Long live the entire Unreal Engine and Epic Games team! You guys are awesome!!! ---

Both methods are totally valid & I recommend both posting here and submitting a report! Also thank you for the heads up on the help button, I’ll see what we can do about getting it to change based on version. The documentation is still getting worked on and updated over time, but if you ever find instances of incorrect examples please tag me and let me know, I can hand that feedback over to the documentation team so they’re aware! I also totally hear you on it being difficult to parse through all of the information, we are working on some possible methods for something in regards to that right now. Once we have more information available I’ll be sure to update yall! Thank you so much for being part of the community, we improve because of folks like you, your time & your feedback! I appreciate it so much! ---
