アンリアルフェス ソウルは8月20〜21日開催、スウィーニー基調講演と42セッション

Epic's Korean developer conference, UNREAL FEST Seoul 2026, runs Thursday 20 and Friday 21 August in Seoul's Gangnam district — the same two days Fortnite spends launching Chapter 7 Season 4, Override. If you build in UEFN, the collision is worth knowing about: the season takes your players' attention and the conference takes Epic's engineers'.

The programme is 42 sessions across four tracks — Game: Art, Game: Programming, Media & Entertainment, and Manufacturing & Simulation — opening with a keynote from Epic CEO Tim Sweeney and Julien Marchand, senior director of framework and systems engineering, after remarks from Epic Games Korea general manager Park Sung-chul. Epic says some sessions stream online, so this is not strictly a room-only event.

What is actually on the schedule

• UEFN is named explicitly in the technology line-up, alongside Unreal Engine 5.8, MetaHuman and Epic Online Services.
• Session topics announced include AI-assisted development collaboration, content creation with PCG, mesh-terrain landscape production, and large-scale crowd work using MetaHuman and the Mass Framework.
• Perfect World Games is presenting open-world optimisation from Neverness to Everness; two indie sessions come from Newcore Games (UI implementation) and Roomton (a cinematic adventure game).
• Registration runs through the Epic Lounge site; the 50% early-bird window closed on 27 July.

The reason a UEFN creator should care

At State of Unreal in June, Epic put its roadmap on the table: Unreal Engine 6 merges UE5 and UEFN into one toolset, with early access targeted for the end of 2027. That is the single biggest structural change facing anyone whose work currently lives inside UEFN — and it means the engine-side sessions at a regional Unreal Fest stop being someone else's conference.

Temper the expectation, though. A regional Unreal Fest is where Epic and local studios explain how things are built, not where the next Fortnite ecosystem policy gets announced. The Chicago event in June was the announcement venue this year; Seoul is billed as sessions and a keynote. Watch the streamed talks for technique, and do not plan your week around a reveal Epic has not promised.

One detail the reports disagree on

The venue is inside the Parnas complex in Gangnam, but the two Inven Global reports name different hotels in it — the Westin Seoul Parnas in the June pre-registration story, the Grand InterContinental Seoul Parnas in the July schedule story. If you are attending in person, check your ticket rather than either article. The dates, the 42-session count and the keynote line-up are consistent across both.

For creators outside Korea the practical takeaway is smaller and clearer: 20 August is a busy Thursday. Override launches, a UEFN-adjacent conference opens, and your island's Discover listing competes with both. Ship your season-facing update on launch day anyway — the attention that season launch brings to Discover is worth more than a quiet Tuesday.
