While I would love to have more activity from the engine devs here, most of the questions posted here are simply a waste of their time… Hell a good portion of the questions are simply a waste of everyones time because they are just badly asked questions that don’t provide enough information to actually answer.
Ideally, paid community team members who are technically competent with the engine would monitor the forum for noteworthy questions and send them to the devs as needed for definitive answers. From my understanding this is basically what the UDN is (was?). Unfortunately it’s anyones guess what the UE community team is up to these days.
