Me and a friend are trying to get a fairly basic avatar uploaded, but all of the custom expressions that use shapekeys aren’t working. Object toggles work fine, and the shapekeys for talking and blinking also work, and everything functions in test builds, but not published builds.

I’ve also had this issue with another, much older avatar that was working but got this problem after an update, and now we’re both having the exact same problem on different computers both testing our own uploads.

Unity editor is 2022 version, VRC SDK version is 3.10.5, the only additional package is EasyQuestSwitch.

You could try uploading a copy with a new avatar ID to make sure it’s not loading an old version, then test a really simple FX animation that sets one shapekey to 100 when enabled and 0 when disabled. If that works in Build & Test but still fails after uploading, it would be a good clue that something is going wrong with the published build or the client rather than the model itself
