I can’t find
never find patch or dlc and packaing doucument.
Think about it.
So here is the answer to your question - Build Operations: Cook, Package, Deploy, and Run | Unreal Engine Documentation this explains how cooking, packing, and building etc works in ue4. Also you may want to find some documentation on the English language you also seem to be struggling on that. One last thing you literally just walked into a room asked for help and insulted everyone who could help you. Just saying probably not the best idea to do that in the future.
Really stupid and complex engine.
actually easier to learn IMO since you dont need to be a programmer and since you dont have to specifically know C#.
not really sure what your trying to say in much of this post aside from the complaining. heres what i tell every unity fan who comes here complaining, if you love unity then work in unity. if its "A stupid engine " as you say then dont use it, use what you like. really no one cares which engine you use aside from maybe the bean counters if you hit it big.
guess OP didnt like the responses they got, they changed their question.
lol he did welp least I can actually read it this time and understand it
Okay dude here is the doc on how patching works Patching Overview | Unreal Engine Documentation and by the way this was literally on same page as the last the link I gave. Just slightly above it. O edit here even more documentation on it How To Create a Patch (Platform-Agnostic) | Unreal Engine Documentation.
