I’m jumping on a project that is currently using Unreal Engine 5.4.2 , and upgrading the project to 5.4.4 at this time is not an option because we’re operating on a tight schedule. However, the Launcher only gives me the option to download 5.4.4 or 5.3.2 but nothing in between, building 5.4.2 from source takes 10 hours on my machine and the build fails with a number of compilation errors despite all instructions being followed, and the version-specific standalone installers allegedly available at dev.epicgames.com are locked behind a $2000 paywall with no way for me to explain to the system that I’m both working in games and not making anywhere near the threshold amount of money.
It’s not possible to install a specific hotfix from the Epic Launcher.
Though would you mind expanding on this part:
Upgrading the engine version of your project can indeed produce unexpected results, therefore is generally not recommended to do mid-development. However, those you mention are hotfixes and not entirely different engine versions. All they do is fixing bugs and improving performance. You shouldn’t encounter any issues after upgrading your project to the latest hotfix of the engine version of your choice. I personally never experienced such a thing, nor saw any reports of it online.
Still, to be safe, you can try upgrading a copy of your project on another computer and see how it goes if you like.
