Expression Capture is a tool for extracting facial expression blendshape coefficients and head movement data from video files for animation in Blender. The package includes a standalone Windows application powered by the NVIDIA Broadcast AR SDK and a dedicated Blender add-on for importing the generated data.

Target 3D models must be pre-configured with the standard 52 ARKit blendshapes for the imported animation data to function correctly. Because the tracking relies on NVIDIA's AR framework, the standalone application requires Windows, an installed NVIDIA Broadcast AR SDK, and an NVIDIA RTX 20-series or newer GPU.
