Perhaps explain what “doesn’t work”, other than that you are totally overthinking things.
Just do, you learn a lot more from that than from twiddling over questions.
Also, since you want explanations, the first point of reference is the ue4 documentation. The second is probably the GC or gamegem talks and papers. It depends on what you are looking for an explanation to.
Aside from that, how about you convert your confused list of questions in an actual list so you can refer to the numbers (since you do have 10 question marks in 1 entry, you are right, who knows what question mark within that I was answering to…)
