What is UDN and why I can't get in?

UDN is mentioned in different threads to say that there are several useful information and downloads there … … but I have no access to UDN and I feel that I am missing some vital information…

cane someone explain that point?

thanks

UDN documentation has been moved to Unreal Engine 5 Documentation | Unreal Engine Documentation, if that’s what you’re asking.

Hi 3dPhilosophy,

If you see any questions here that are asked or answered by UE4-archive, then those are posts that were made during our closed beta test of the editor (codenamed ‘Rocket’). These questions were asked on the now-disabled RocketUDN, which was basically another copy of the AnswerHub just for the Beta Testers.

When we made the AnswerHub, we decided to copy the beta posts over so that valuable information would not be lost. However, that also means that some information in them will be outdated, and all links to other beta posts will be broken.

Sorry for any confusion or inconvenience this may cause. You may still be able to find the post you are looking for by running a Search.
