We've just released VRChat 2021.2.2, 1095-- the Udon Networking Update is now Live!
This is the Udon Networking Update! Don't let the name fool you, this long-awaited release isn't just about improving networking for Udon. As you'll see in the full release notes, "UnU" is a massive improvement to many systems in VRChat that rely on networking, and an overhaul to many of our networking systems.
This update contains a huge amount of "under the hood" changes to improve networking behavior and add some long-awaited features to Udon. As such, it might not seem very flashy in terms of new user-facing features, but rest assured that our Udon-savvy creator community will quickly show off what they've been working on during the UNU testing period.
Due to the complexity and technical nature of most of the changes, this summary changelog will seem short. For the full list and more details, please see our full change log.
Client Changes, Fixes, and Improvements
- Generally speaking, networking has been improved in all situations and there will likely be many bugs that are now fixed that we're not listing here!
- Synced objects (as in, objects that transmit their position over the network) should be smoother in all situations
- The "network voice bug" where all voice and IK for users in VERY busy instances would freeze/degrade badly should occur much less (or not at all!)
- Portal entry is now more reliable, especially when moving fast or when your framerate is low
SDK3 and Udon
- Array variables can be synced! Check out the new networking docs for more info
- New Manual Sync Mode for UdonBehaviours
- Many fixed ownership transfer bugs
- Improved the reliability of syncing who the owner of an object is
- New VRCObjectSync component for simple syncing of transforms in SDK3 worlds
- Improvements and fixes to join-in-progress behavior
- New debugging tools
- ... and a lot more!
