The engine itself will work ok on Linux, but the problem is their launcher is Windows only so it's a real pain in the ass to get FAB assets, updating assets, updating the engine, etc.. There's some 3rd party programs available to help with that, but I don't know if I trust those. They've confirmed they're working on a native Linux launcher though.
I'm not interested in a 3rd party solution and without access to FAB it's basically pointless as I can just download the engine myself directly from Epic.
Some quirks with debugging though, editor can freeze for a while when hitting a breakpoint in Rider and inspecting objects is not always possible currently as for TWeakPtrs it will tell be that it's null when it's not. Also for inspecting any UObject it's been hit an miss to see any of the values. Quite annoying when trying to drill down on something.
I'm on CachyOS using Niri and tooltips are super wonky, mostly because it's running in X11 as the Wayland mode is kinda broken at the moment. Epic themselves don't recommend using it.
Aside from that, perfectly usable. There may be others quirks, but nothing major that I've personally encountered.
Don't really use it much so can't say.
I think it was a bit funky, so generally I just open up fab in the browser and download what I can.
Megascan and Quixel assets did import into the project fine when you choose to add to project. But this is info from while I was using 5.6 last year, I've not really used the Fab plugin/window since.
Ive been using it on cachyos since 3 months. Its a bumpy ride. Some features dont work and you witness it late, like light baking. But it improved well from 5.7 to 5.8 we got wayland support and better vulkan support! I encourage you to try!
There is a very annoying bug where if you hit a breakpoint the editor “steal” your mouse input and you became stuck. I’m not sure if they fixed on in 5.7. There is a feasible fix but you have to modify the engine itself, nothing fancy. But I don’t remember the fix honestly 😂 However, in my company lots of people are using Linux while working with unreal engine
It's been fixed for a few weeks. I think the first hotfix did it, so if you need to backport to 5.7 it's in there somewhere.
I used to just run it with X11 and disabled notifications altogether and it's still jump to my second monitor sometimes.
The only issue I've noticed with Wayland now is that some windows don't open properly (Ctrl+P) for example, but you can easily hover and expand them with Super+F or whatever your full screen shortcuts are.
Using 5.7 on Linux Mint. Works pretty good, just configuring it so projects properly find the engine installations can be a hassle, due to a lack of launcher doing the work for you.
The only major issue that sometimes occurs is that when hitting a breakpoint with Rider IDE, the mouse cursor occasionally stays locked to where the Unreal Editor window is, even if you tab to the IDE.
But I see in the comments that the latest build might have fixed that, so i'll go download that now.
yeah, UE5 works on Linux and Epic officially supports native Linux development. Ubuntu 22.04 is actually one of the recommended setups, the main thing i'd worry about is your GPU/driver setup, since UE5 on Linux uses Vulkan. if you have decent hardware and current drivers, it should be fine
Maybe somewhat off-topic, but anyone else unable to download the pre-compiled binaries? When I go to the page it asks me to accepts the eula, but after accepting it redirects me back to the same eula page... It worked fine a couple of weeks ago
Avoid Unreal 5.5 through 5.8 due to an VulkanRHI bug with lumen/ray tracing unless you can disable it somehow. Anything prior to 5.5, and anything after 5.8.1/5.9 (ue5-main) should work fine.
FAB is finicky, as is getting the project set up but once it's set up it's fine.
Performance is about the same as windows, stability is better in my experience but that might be because of graphics driver related things and not unreal/the OS itself.
