![]() ![]() There are several options to download Marketplace content natively: The marketplace apps can be downloaded using the launcher on Windows (or Mac), they are stored in /Program Files (x86)/Epic Games/Launcher/VaultCache/. The launcher with the Unreal Marketplace is not available for Linux yet, so apps like the ContentExamples project cannot be installed from Linux. The StarterContent project is installed to /opt/unreal-engine/Samples/StarterContent/StarterContent.uproject, you can browse to it from the launcher. To fix the big blank window go to Edit Preferences > User interface > Enable Window Animation and activate the checkbox Source: Blank window in Blueprint with multi-monitor configuration They can be disabled by adding toĮngine/Config/ConsoleVariables.ini Slate.AllowToolTips=0 Random freeze under KDEĭisable index file content in the KDE file search options.Įpic suggests allowing compositing for the Unreal Editor, which is stopped by default. UE4's mouse-over tooltips might be rendered very slow. Launch your project and accept the rebuild If it does not work, check the file Engine/Source/Developer/DesktopPlatform/Private/DesktopPlatformBase.cpp in your Unreal Engine source code, look for the line `Arguments += " -Progress -NoEngineChanges -NoHotReloadFromIDE" ` et remove the two last options : `Arguments += " -Progress" ` Please build through your IDEįirst, in your source folder in your project, check that Note that completing both of these rebuilds can very well take over an hour, depending on your system specs.Įngine modules are out of date, and cannot be compiled while the engine is running. Afterward, it will open and ask you to rebuild the project class, after which you can actually start working on your new project. Do not abort this build, or you will brick UE4 and will need to reinstall unreal-engine. ![]() If while trying to open the project in UE for the first time, you get a message about editor modules being out of date, you need to build the UE4Editor target in your IDE. The CPU usage should show that it is still compiling, and you may want to launch the editor from a console to see progress. After re-launching the editor, the new project shows up and can be opened, but on the first run, it takes a half-hour or so to compile, and since this happens in the background (no GUI) it might not seem to be doing anything. ![]() $ /opt/unreal-engine/Engine/Binaries/Linux/UE4EditorĪfter creating a code project, the new project opens in a text editor instead of in UE4Editor as it should. If the editor does not start from the menu, or something does not work right, start it in a console and check the output for errors. However, this might have some performance impact.Īnother approach would be to use different clang version (e.g. If the compilation fails you should try building the Editor using the Debug profile : (This does not include shaders compilation) The compilation can take from 20 minutes up to a few hours depending on your machine.Īs an example on a AMD FX-8350 (8 threads) with 16GB DDR3 on a SSD and Clang 3.8.1 takes roughly 40 minutes. Note that this link will not work unless you first follow the steps outlined above. ![]() Since the repository is private, you can set up an SSH key so your GitHub account is used to download the source.įor a smaller download you can use. This AUR package downloads ~10 GiB of source files plus ~5 GiB of dependencies. The package is ~70 GiB installed (after compiling shaders on first launch) and needs ~120 GiB to build with an output ABS package of ~9 GiB when compressed. # chmod -R a+rwX /opt/unreal-engine/Engine You might have to fix permissions for UE4 to precompile shaders on first launch: Unreal Engine 4 is available in the AUR as the unreal-engine-4 AUR package (or unreal-engine AUR for UE5 version). This will compile the Unreal Engine and the Unreal Editor. An invitation can be acquired by linking a GitHub account to an Epic Games account. Note: Access to the private repository requires an invitation to the Epic Games Organization. ![]()
