Animation works in unity but not in vrchat

Hey, so I know I’m not the only one with this issue—I’ve seen a few posts about it, but none had a fix. Here’s what’s happening.

I made an animation on a separate model (not the one I uploaded), imported it into Unity, and attached it to my main model. The idea was to have the main mesh disappear while the secondary mesh plays the animation, plus some particles for extra flair. It’s tied to an int toggle, for what it’s worth.

But when I test it in VRChat, only half of it works:

  • The main mesh vanishes like it should.
  • The particles play fine.
  • The animated mesh? Just… stands there. No movement at all.

Anyone else run into this? How’d you fix it?
