Replying to posts is not a job, users don’t get paid for it. If someone has a free moment and knows the answer, then answers. He devotes his free time, so it would be appropriate to respect it and not to make a fuss that “throw out you work and gimme a reply now!!!”
On SO you will get the answer faster because:
a.) the questioner puts up a code (even MCVE) that you can copy and run online in less than minute. (undoable with UE4)
b.) ONLY and ONLY specific questions are posted (applying SO rules on this forum would result in throwing-out approx. 70% of topics)
