I like the look n feel of the environment you created @ DevilArx
looks interesting, good job!
don’t know what is going wrong with your packaging but 7 errors & 544 warnings isn’t good. always try to build & save often while you’re making something in UE4.
sometimes you can catch what’s causing the problem quickly & isolate then fix before it becomes a huge problem. & try to allow for a test packaging of your game when time allows. anyway good luck on your work
