UE5 (Unreal Engine 5 Game Engine)

Ashe commented 3 years ago

Project description Now that we have access to Unreal Engine 5's source code, it would be nice to have a ue5 package which corresponds to the main branch of UE5 ue5-main.

The quick start documentation shows some steps to getting it working, however as a NixOS newbie I got stuck when it begun requiring things of dotnet (I also wasn't making a package which was just making my life more difficult).

Apparently the stages to get this setup are:

Clone the branch

Run Setup.sh in the root folder

Run GenerateProjectFiles.sh in the root folder

Run make

Some things to note:

Their scripts use /bin/bash which need changing to be /bin/sh (or maybe there's a better way of doing this with Nix)
There are internal programs for mono and dotnet (I think), however I couldn't get these working. Trying to use my own versions of these sort of worked but never fully got things working

Would love to see this! Thank you!

@dyaso was the startup crash happened before or after the project selection/creation page?

juliosueiras commented 2 years ago

@dyaso I pushed a new commit try that one(just incase), it won't trigger the base(120ish GB) rebuild

dyaso commented 2 years ago

Oh sorry, that was during the first splash screen, before project selection.

Your new version seems to've fixed it, i got to the project window and made and ran a Blueprints 3rd person template project, and the content examples Niagara Advanced particles demo level also runs fine.

Btw, just found out that if one wants to use the handy send2unreal Blender extension, you have to enable a port for IPC by adding networking.firewall.allowedUDPPorts = [ 6766 ]; to configuration.nix

Just saw there's been a hotfix release with release notes mentioning fixing "[Build Blocker] Compile UnrealHeaderTool Linux - Failed to load app-local ICU". Might that help with getting C++ games working?

Before it starts compiling, you need to update the release patch number in unwrapped.nix and its SHA to 12c15d51gywbhkbvsjqgr7y26d9v9k4g514j91rh311gzfyixsfj , change

    url = "http://cdn.unrealengine.com/Toolchain_Linux/native-linux-v19_clang-11.0.1-centos7.tar.gz";
    sha256 = "tlDwsQKpXi8qKQ3Ywe5BKYx1lnzr4Z8kIA6jqEkBRhM=";

to

    url = "http://cdn.unrealengine.com/Toolchain_Linux/native-linux-v20_clang-13.0.1-centos7.tar.gz";
    sha256 = "0ygnmmf8h66nk0ba8yl58q3y6ny2mb23ikzak9pa3fxrm624brid";

and update the line cp ${clangBundledToolchain} .git/ue4-sdks/v19_clang-11.0.1-centos7.tar.gz in the same file similarly to the new name,

and add xdg-utils and curl to fhsenv.nix

plus add these 158 entries to `cdn-deps.nix`

Nb: i got this list by modifying this shell script from the `ue4` derivation to not redownload things which were already in the store. Since the 5.0.2 list of things is 5748 items long and the 5.0.1 list is 5724 long, this means there'll be 134 unneeded things left in the store, i think?

Perhaps if i could open a nix-shell in the wrapper environment i could run UnrealBuildTool by hand, or possibly modify it to correctly write to ~/.config/unreal-engine-nix-workdir/ as intended? Idk how to do that though.

@juliosueiras what "tweaks" did you use to get C++ projects working?

juliosueiras commented 2 years ago

@dyaso yea, the error is cause because we need to remove a few specific files/directory in the linkage, to let UE rebuild again because UE like to modify itself

juliosueiras commented 2 years ago

will take a look at the hotfix release

dyaso commented 2 years ago

Managed to get it creating a C++ project without errors: I used this script

#!/bin/sh

replace_with_store_copy () {
    config_copy="$HOME/.config/unreal-engine-nix-workdir/$1"

    if [[ -L $config_copy ]]; then
        store_copy=$(readlink $config_copy)
        unlink $config_copy
        cp $store_copy $config_copy
        chmod +w $config_copy
    fi
}

while IFS= read -r line; do
    replace_with_store_copy $line
done < "$1"

to replace these files with the store copies

Engine/Intermediate/Build/XmlConfigCache.bin
Engine/Binaries/DotNET/UnrealBuildTool/UnrealBuildTool.dll
Engine/Intermediate/Build/BuildRules/UE5Rules.dll
Engine/Intermediate/Build/BuildRules/UE5RulesManifest.json
Engine/Intermediate/Build/BuildRules/UE5ProgramRules.dll
Engine/Intermediate/Build/BuildRules/UE5ProgramRulesManifest.json

Unfortunately the IDE (vscode) that then opens says "Make not found.", and trying to compile the project from within the editor produces

ERROR: Unhandled exception: System.UnauthorizedAccessException: Access to the path '/home/user/.config/unreal-engine-nix-workdir/Engine/Intermediate/Build/SourceFileCache.bin' is denied.

Before i try replacing a bunch more things: is this similar to the "tweaks" you did, or am i going down the wrong path?

Downloading the binary from https://www.unrealengine.com/en-US/linux, and just running DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 steam-run ./Engine/Binaries/Linux/UnrealEditor everything seemed to work out of the box, including c++ projects and vscode! Screenshot from 2022-07-20 14-23-04

juliosueiras commented 1 year ago

@vlinkz that would be one option(though the issue mostly would be the fact that it will be binary package, the steam-run is not much of a big issue)

juliosueiras commented 1 year ago

(I am fine with the binary approach, since it would be smaller and faster)

juliosueiras commented 1 year ago

(XD just realize, it will still be the same issue, since you are running directly, but the package will be in nix store and Unreal like to edit the engine in-place)

vlinkz commented 1 year ago

Maybe instead packaging something like Epic Asset Manager would be better. I heard the dev mention that with the new binary releases, they were planning on implementing direct downloads and version management in the app

Please note that, at the moment, Epic doesn't include Quixel Bridge in the precompiled binaries which EAM also uses, so it is still pretty important to get it compiling with nix.

Hey, this is awesome! I'd love to be able to use UE5 on NixOS. Has there been any progress?

Working using new nvidia official method nvidia-offload instead of now deprecated bumblebee on x11, running the following command:

DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 nvidia-offload steam-run ./Engine/Binaries/Linux/UnrealEditor

nvidia-offload in my case is just a script located in path that set the following env variables:

__NV_PRIME_RENDER_OFFLOAD=1
__NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0
__GLX_VENDOR_LIBRARY_NAME=nvidia
__VK_LAYER_NV_optimus=NVIDIA_only

my laptop has a 1060 MOBILE and an i7-8750H with 16 gigs, so if you got a similar setup, this should work.

Maybe instead packaging something like Epic Asset Manager would be better. I heard the dev mention that with the new binary releases, they were planning on implementing direct downloads and version management in the app

Did this end up being the case? Is anyone successfully using UE5 on NixOS beyond just seeing if they can?

I got it to work somehow with a nix shell, but I don't see myself using it for production like this. It also seems like some features were not working well because not properly ported to linux and Vulkan on Nvidia GPUs for instance. It seems it might work better on an Ubuntu based distro though. If anyone has more news please share them.

NixOS / nixpkgs
