+1 vote for Linux launcher . I’ve tried running it running it on wine with no success. Would love to be able to download the Infinity Blade files for the Cinematics tutorial videos. v4.14 runs like a dream on Ubuntu 14.04 with radeon driver. Tried v4.15 but the graphics are garbled, I think that’s more likely to do with me than UE4, so went back to 4.14. Other than that, very happy with the Unreal Editor on Linux.
