Blender addon to receive VRCFT data and modify a mesh's shapekeys in realtime

VRCFT OSC Receiver

VRCFT OSC Receiver is a Blender addon to receive OSC data from VRCFaceTracking and modify a mesh's shape keys accordingly, in real time!

Installation

Simply download the latest release from the releases page and install it like any other Blender addon!

Configuration

Configuration is fairly simple! Just input the mesh you wish to preview, and then click start! Make sure you already have VRCFaceTracking up and running to avoid any issues! If you wish to use a different port, you can change it in the addon preferences. If your shapekeys have a prefix, you can also change that in the addon preferences.

vrcft-osc-receiver's Issues

Exception after a split second

After selecting a mesh with all the shapekeys and starting the OSC server, it successfully receives a few frames of face tracking data from VRCFT. Then the addon quickly runs into this exception which causes it to stop:

Exception in thread Thread-19 (recv_and_process):

I tried 3 different models and the same thing happens, but "Key.001" in the exception may be "Key".
