Installation
Install via VCC / ALCOM (recommended)
Open Add to VCC / ALCOM and register the repository. If you have already registered it, continue to the next step.
In your project's package management, find "Avatar Blink Fix" and add it with the + button (typing "blink" in the search box gets you there fast)

+ button disabled / "nadena.dev.ndmf not found"
Avatar Blink Fix requires NDMF. If the NDMF repository isn't registered, the package can't be installed together with it.
Register the NDMF repository,
https://vpm.nadena.dev/vpm.json, in VCC / ALCOM as well. Then press + again.Open the project in Unity. A fresh install runs as the free edition, so you can try it before buying.
Installing via unitypackage
A unitypackage is also bundled for those not using VCC / ALCOM. Import it into your project and it works as-is. You'll have to re-import it for every update though, so VCC / ALCOM is easier unless you have a specific reason.
Upgrading to the Complete Edition (for buyers)
Upgrade to the Complete Edition (importing the unlock key)
Updating from 2.x
Import 3.0 without removing the previous version. If a migration prompt appears during installation, click "Migrate." You can keep using your existing data and settings.
For a new project, simply import 3.0.
Next step
Once installed, head to Auto Fix (Recommended).
System requirements
- Unity 2022.3 (the VRChat-supported version)
- The non-destructive features (Auto Fix, Auto Fix (Bake Mode)) require NDMF
- Without NDMF, Mesh Swap (Legacy) still works (when installed via unitypackage; installing via VCC / ALCOM brings NDMF in automatically)
