I am new to UE community. Dont’t know which is the best place for asking utter newbie (to UE) questions. Where is community most active?
Both are pretty active so I would say it has more to do with what type of question you have. If it’s a quick question or you want to get some feedback on whether you are doing something correctly, use the forums. For any technical questions (issues with the editor/launcher, bug reports, how-to questions) AnswerHub would most likely be the best place.
If you don’t get a response you can always submit a question on the other one, it’s good to leave a link to your original question as well when you do this. Hope that helps!
ps. I’m going to move this to General Discussion since it is not a Blueprint question.
Also take a look at this thread: What's the purpose of having the forum AND the answer hub? - General Discussion - Unreal Engine Forums
-post during the week -> over the weekend not many people are online
-in the forum you get the answer a little bit faster (in my opinion :p) -> but bugs should be directly posted onto answerhub!
