[1865/Open-Beta/Unity 6] Major avatar animator desync regression in large instances (60+)
complete
~Nanochip
There has been a major avatar animator desync issue in large instances (60+ players). It seems quite random with who it affects, some players are not desynced (their animations/toggles/facetracking show just fine) and some players are in their default upload state.
To reproduce, join a very large instance and you'll notice several players in their default upload state, by asking around or recognizing friends' default avatar.
Players that are on the live build 1865, open-beta, and Unity 6 branch can see other players desynced AND they themselves can be affected by the desync.

VRChat is hosting an event to test this bug at the "Capcity Stress Test Pop-up" [sic] event tonight.
"There will be something new being experimented with this time‚ an adjustment to make avatar parameters scale better in larger instances․ For this bring out your avatars with cursed setups‚ specifically around the usage of sync'd parameters‚ expect some to break but I'm curious how they break․"

This has been addressed with server-side changes.
The cause was twofold:
- Some increased traffic on our end
- The usage of "parameter compressor" tools.
Parameter compressors are inherently unstable. While we understand the desire to use them and the reasons people feel they need to use them, they introduce significantly increased risk of desyncs, especially in unstable network conditions.
Please keep this caveat in mind if you choose to use these tools.

Out of curiosity, can you find out if afflicted avatars are relying on Parameter Compressors? (VRCFury or other tools) These systems are very hacky/delicate so if animator updates are modified in some way, they may break.

I've had this happen to me too. If I have my culling wide enough I can see someone's avatar but its in default upload unless I force show them.
