LiveLinkFace is an add-on that connects the iOS LiveLinkFace application to Blender, enabling real-time facial motion capture. It allows users to stream ARKit blendshapes from an iPhone equipped with a TrueDepth camera to any 3D mesh set up with matching shape keys or bones. Users can also import pre-recorded animations using LiveLinkFace-formatted CSV files.

The expanded version of the tool provides additional workflows for facial animation production. These include recording live animation streams directly into Blender actions, applying filters to smooth out jerky captures, and setting up drivers for head and neck rotation. It also features a blendshape remapper, which allows the tool to drive meshes that use non-standard naming conventions for their shape keys.
