All tutorials are accessible online afaik.
I see that I can buy stuff from the Marketplace online, but I don’t know if I can download it on Linux. On Windows when I press <Download> button it launches UE4 Launcher.
I am pretty sure if it works under WINE, you can do everything there, but you also have to run UE4 for Windows, or manually copy whatever you downloaded into WINE’s folder, from there into your UE4 Linux folder.
It’s inconvenient, but let’s face it - Linux market is 2%. And that’s gamers. So most likely .5% is developers. So, 99.5% develop on Windows and OSX, and .5% are on Linux. Who do you think will get first? Remember, Epic is a business, they are not FSF.
I bet that after Paragon is out, Rift / Vive are running smooth and maybe UE4 is ver. 4.15 or greater, Epic might get back to Linux. Which I am totally fine with. There are lot more things need to be sorted out for platforms that are profitable, before getting back to platforms that are complimentary.
As long as UE4 can deploy to Linux, and Linux builds run fine to satisfy Linux gamers, it’s cool. That’s why I switched back to Windows - to focus on making games and not fighting software or waiting.
