I cannot get this to work in 5.4 - tried exporting from blender as stated - and it no worky. Saaaad :'(
I cant remember the error that comes up in Unreal Engine but something about bones or rigged. I'll edit this later once I'm home
Definitely had good elements, the puzzles were different which was great. I like the look of the graphics too. The only issue I had was the mouse sensitivity was slow. I had to do huge arm swoops to turn the character. I had my mouse set at 1400 via Hyper-X software and went to 1600. Didn't help. But great game though!
