VRChat Quest Open Beta Moves to Unity 6 Ahead of Creators

Mixed News reports that VRChat has moved its Quest STANDALONE client onto UNITY 6 — but only on the OPEN BETA branch, and only for players who OPT IN. Per VRChat’s release notes for Build 1913 (dated September 15), the regular OpenBeta branch for testing Quest in standalone mode now runs Unity 6000.0.67f1.

The Separate unity-6 Branch Is Closing

Unity 6 builds had lived on their own opt-in branch. VRChat now says Unity 6 is “now STABLE enough that we consider it ready for the regular open-beta BRANCH,” so the dedicated unity-6 branch will CLOSE and ordinary beta branches will hand out Unity 6 builds instead. The HEADSET is the new piece: Unity 6 “is now AVAILABLE on Quest,” putting the headset BUILD on the same ENGINE as the rest of the open beta.

That engine swap sits underneath every WORLD and avatar. The client is a Unity application, so the version decides how content is drawn, simulated, and held in memory on Quest’s own chip. A BETA build is where that change happens first.

Creators Must Stay on Unity 2022

Nothing moves on the SDK SIDE. VRChat’s Build 1913 notes warn, with the typo intact: “Do NOT upgrades your SDK projects to Unity 6. It will not WORK.” The current creator editor remains Unity 2022.3.22f1, as listed on VRChat Creation docs. Upgrade a PROJECT to match the client and the SDK cannot USE it.

So the CLIENT engine and the SDK engine sit on SEPARATE CLOCKS. VRChat has given no date for Unity 6 support on the creator side, and no date for 2026.3.3 leaving BETA.

Build 1913 Fixes — And What Still Isn’t Live

Official VRChat 2026.3.3 Open Beta notes list Unity 6-related FIXES in Build 1913: a CRASH during world LOADS, a crash tied to certain BUFFER particle setups, and a TextMeshPro.renderer access issue for Udon. Frame RATE with high polling-rate mice is better but “not properly FIXED,” with VRChat still working with Unity and Microsoft.

None of this has shipped to the wider player base. The current LIVE release is 2026.3.2 from September 1. The beta kept moving after 1913: Builds 1914 and 1915 landed September 18 — the second Steam-only, fixing intermittent SteamVR soft locks. Until 2026.3.3 goes LIVE, Unity 6 on Quest is something you SWITCH ON yourself.
