Two Meshwright add-ons for VRChat face tracking in one set. FaceKeys Full makes the face tracking shape keys. BlinkMend repairs the blinks and the other eye keys after you edit the face. Bought separately they cost 50 USD. The set is 45 USD.

What each tool does

• FaceKeys Full: makes face tracking shape keys in one click: all 102 keys with the exact names of VRChat's built-in face tracking, ready for Auto-Fill, or ARKit (Perfect Sync) names, plus the 15 VRChat visemes. Anime, VRoid and realistic heads.
• BlinkMend: rebuilds every eye-closing shape key for an edited face in one click: the blink, both winks, the smile eyes and the face tracking eye keys. For bigger eyes, jitome eyes, moved eyes and face sliders. The lids meet again and stay off the eyeball.

Why they go together

Face tracking closes each eye on its own, so a blink that stops short or a lid that cuts into the eyeball shows at once. BlinkMend rebuilds eye keys under ARKit names (eyeBlinkLeft) and Unified Expressions names (EyeClosedLeft) too. Those are the names FaceKeys writes.

What you get

• 2 add-on zips, the same files as the single products: FaceKeys 3.0.0 in the Full edition and BlinkMend 1.0.0.
• The same updates: every new version of a tool is added to the set too.
• Each zip installs and works on its own.
• Blender 4.2 to 5.2. English and Japanese interface in both tools.

Price

45 USD for both. Bought separately: 50 USD (FaceKeys Full 35, BlinkMend 15).

Good to know

• FaceKeys writes all 102 of VRChat's tracking keys since version 3.0 (a free update). What moves depends on the avatar: on a VRoid-style avatar 98 keys move. The 4 throat and neck keys stay empty, because a face mesh has no throat or neck. Details are on its product page.
• Not sure what your avatar already has? FaceKeys Check is free on the FaceKeys page. It reads the key names and changes nothing.
• Each tool's tests and limits are on its own product page. Please read them before you buy.
• Own FaceKeys already? Then BlinkMend alone is the cheaper way.
