We're actually mirroring the vast majority of them since we introduced it (we're not mirroring old tickets since they might contain sensitive information).
We're severely limiting the number of private tickets studios get.

Haha, luckily UDN posts are now mirrored publicly on the Epic Developer Community once resolved.
But you're right, that's a recent change, and it was exclusive to custom licensees (which mostly AAAs could afford) before.

Game devs in AAA: What are some misconceptions or fun facts about your industry?

I'll start: We don't have exclusive learning resources; we're watching the same YouTube presentations and online tutorials as everyone else.

Words cannot describe how happy I am with the standing-room only crowd @mattoztalay.bsky.social and I got for a PROFILING talk! 😲

Huge thanks to Arctic Hazard and Tripwire Interactive for letting us show profiling data from their upcoming game, NORSE: Oath of Blood 🙏

Sometimes your heroes don't recognize you, and that's OK! Just be chill about it. Don't be like me when I met @timsweeneyepic.bsky.social. He's so famous! Uhm, do as I say, not as I do 😅

One week until Unreal Fest Stockholm! I'm so excited because I heard that Jack Condon will be there 🤩
Hmm, I wonder if I can get him to guest-cameo on stage with me 🤔

so many devs treat perf this way, like a series of unquantifiable acts of god

I couldn't even speak straight when I met the one, the only, the most FAMOUS @highlyspammable.bsky.social ! 🤩
I think he even glanced my way *swoon* ❤️

Unreal Fest Stockholm is SO CLOSE! I can't wait to meet all the cool people there.

Looking forward to seeing some of y’all!

Ari Arnbjörnsson @flassari.bsky.social · Sep 8

Whoa, I ran into @phyronnaz.bsky.social in Orlando! He made the Voxel Plugin for Unreal!
So many cool people to run into at Unreal Fest. And it's only two weeks now until the next one in Stockholm 😯

Late to an online meeting again? So embarrassing!
A 10-minute default heads-up is way too much time when I just need to join a Zoom.
Pro life hack: Go to the calendar settings and set the default notification time to 2 or even zero minutes. Never be late to an online meeting again!

If you see this dialog in your Unreal Engine project, click Install. At Epic Games, we now ensure that the preferred toolchains for the current engine version are listed in the Visual Studio solution. #uetips

This is how my game dev journey started.

When I was 15, I got a trial version of Flash, created this short with my friend on his computer, and submitted it to newgrounds.com. It scored 2.06 out of 5 😄

And now I work at Epic Games! 😮
What ignited your game dev career?

Even though there will be many Epic folks at Unreal Fest, I'm also excited to meet the community people! Like when I ran into @gamedevmicah.bsky.social in Orlando 🤩
