VRChat Avatar Kit: documentation

Install

1. Edit > Preferences > Get Extensions.
2. Open the menu at the top right and choose Install from Disk.
3. Pick outfit_refit-2.0.1-standard.zip. Repeat for facekeys-2.1.1-full.zip.

Each add-on adds its own tab to the 3D Viewport sidebar (N key). They install side by side and work together in one file.

Which one when

• The outfit was made for another base: use Outfit Refit. It moves the outfit onto your avatar, gives it weights from your avatar and makes it follow the body shape keys.
• Face tracking: use FaceKeys. Select the face mesh, set Landmarks to Anime for anime and VRoid avatars, pick VRChat (Unified Expressions) under Names and press Generate Shape Keys. In Unity, Auto-Fill Blendshapes in the Face Tracking section of the VRC Avatar Descriptor maps the 75 keys.
